How to feel good?

When you feel good you perceive, process and think in a healthy way. Based on this you have inner clarity and that allows you to life live in a healthy and enjoyable way. When you feel well & good you have access to all your inner resources and it´s easy and natural to “do good” – to feel, think and act in a way that is pleasant for yourself and fun for the people around you.

Your basic feeling depends mainly on 3 neurotrasmitters: dopamine, serotonine & GABA.

It´s really that simple. The presence or absence of 3 amino acids in our brain determines what appears real to us. What IS our reality. How we perceive it and how we function in it.

Dopamine regulates everything related to motivation, pleasure, energy and drive. You sense the presence of dopamine by a natural feeling of exitement and enthusiasm. You are looking forward with a positive attitude. You can´t wait and you feel energized. You want and you know that you can. This is dopamine in action.

Serotonine regulates happieness and satisfaction. It supports a well balanced positive attitude. It makes you smile and feel safe. No matter what happens around you – with the presence of serotonine you feel capable of dealing with it in a light-hearted way. You feel complete and ready for anything.

GABA plays an important role for relaxation, stress-reduction an inner balance. It supports cognitive work and focus. It helps to take it all not too serious and act from a relaxed inner place. It helps to calm down after challenging experiences. With the presence of GABA it is easy to swich between tension, at-tension and relaxation after. It allows you to go full force on a difficult task and totally relax after it and have a short nap.

Those 3 neurotransmitters totally control how you feel. Due to the right exercises and the right diet you can support the balance of these 3. But there is also a biochemical shortcut. At the moment it might be beyond your imagination how profound the changes are, when you have enough of this 3 amino acids in your brain. In order to be able to produce a sufficient level of these 3 neurotransmitters you need to have the basic building blocks in your system.

Dopamine depends on L-Tyrosine. You need also vitamine B3 & B6, magnesium and zinc to produce it. It´s build in the body as follows:


Serotonine needs L-Tryptophan or 5-HTP. The building is supported by vitamin B6, D and zinc.


GABA is build from L-Glutamine. Production needs also vitamin B6.

L-Glutamine → GLUTAMAT → GABA

These 3 amino acids can come from a well balanced diet (details here) or in form of supplements. You can just buy L-Tyrosine, L-Tryptophan (or 5-HTP) and L-Glutamine. It comes in form of capsulas or as powder for oral application.

Combine this with B3, B6, D, magnesium and zinc and you will be surprised how quickly and profoundly your feelings change. This knowledge has the potantial to totally change your life.

How to stay calm in any situation

What happens when we face massive fear, threat or stress? We are running away, or freeze or fight. All therapies in essence support and enable the client for forward confrontation – to face the facts and work through the situation. To stay present and deal with the situation, to fight through it (or even your own mind and patterns and trauma and history).

To lean into the friction in healthy and adaptive ways. To embrace the challenge and transform it. To change your behaviour forever. Since a while I am heaviely inspired by the work of neuroscientist Dr. Andrew Huberman. He is a brilliant mind and an amazing human being. Check him out on Joe Rogan and Lex Fridman Podcasts. So much increddible work from him is out there for free. Here he describes a simple and effective way to get yourself in a state where you are able to process ANYTHING. Lateral eye movement. (He also delivers the scientific background, why EMDR therapies work.)
To even at the same time release dopamine and get immediately rewarded for this action of forward moving/confrontation, while getting yourself in a hightend alerted but relaxed state of being. Meaning to have access to optimal brain performance. To basically temporary deactivate your amygdala, your threat detection center. Try it out the next time you feel troubled. Here some more background about the why and how:

DMT – the “spirit molecule”

This tryptamine alkaloid produces an intense psychedelic experience when ingested, and appears in trace amounts in human blood and urine, suggesting it is also produced within the body itself.

It´s the stubstance that gives Ayahuasca it´s power and you can consciously produce small amounts of it it in your body by using breathing techniques. Holotropic breathing and Wim Hof breathing are the most common methods I am aware of.

Depending on the amout of DMT you have in our blood you can enter different states of consciousness, perception and insight. Usually these experiences go along with all kind of geometric visuals which you might now already from other trippy experiences.

I came across this highly interesting video where a young student from the Harvard Science of Psychedelics Club explains the connection between the quality of the visuals you get and the state of being you are in. It´s a pretty good and precise map and might be helpfull for you to keep track where you are and what are the specific qualities of the level of consciousness you temporary entered. Welcome to the hyperbolic geometrie of DMT experiences. Enjoy your journey!

How does neurohacking look like in practise?

In this post I´ll do my best to clarify how neurohacking looks like on a practical level. First of all it is an ongoing journey which includes a critical review of behaviour, habits and mental & emotional patterns. It starts with a radical honest review what is going on in you right now. That includes to have a close look to all kind of addictions, of diet, of daily routines and how much this supports or drains the free flow of life energy. It is about understanding how the body works and how he reacts to the way you treat him. The next step is to gain deep understanding how your brain works and how this is affected by the state of your body and by neurotransmitters.

Neurotransmitters are the key – they essentially are responsible for switching on or off different brain areas and by that fully shape your perception of life and your way to deal with it.

So selfreflection and ongoing studies how the body and brain works give the base for an educated guess what is wrong with you here and now or with other words for a detailed analysis which areas how you treat yourself could and should be improved. When the problems are identified properly it is not that difficult anymore to find solutions how to improve your physical, mental and emotional health.

These possible solutions can be split into 2 categories: practical rituals & excercises for the body & brain and finding the right diet & supplements which support your system to run in a very efficient (and by that pleasant) way according to the life situation you choose to be in.

Rituals & exercises can include things like yoga, workouts, breathing techniques, walks in the nature (or body movement at all), aligning with natural rythms by watching sunrise and sunset every day, conscious meditations or practises with a specific intention, realistic goal setting and time management to name just a few. In short it is about the development of healthy habits.

The diet & supplement work is the other main part of neurohacking. A healthy diet according to your body type, your job and your life reality is the base. Let me explain what I mean by “supplements”: Every molecule we put into our body has an effect on it – eighter directly on the brain or indirectly by affecting the body and by that affecting the brain. It is a fluent spectrum without clear boundaries what we call nutrition / herbs / supplements / medicine / nootropics / drugs. All of it has an impact on how the brain works. All of it has effects and also sideeffects which need to be taken into consideration, too. None of it is a solution forever (maybe except vitamins who are a good thing all the time) – it is always about adressing a specific goal / intention here and now.

The idea is to find a way to come to a corrective experience with your body and brain with the help of whatever is needed – in order to incorporate this experience into your future life. Meaning once the body and brain are remembering how it can feel it is way easier to come to this state again and again without specific exercises or supplements. It is about actively healing yourself and constantly improving yourself into the being that you really are – an empowered, authentic, loving human being who enjoys and celebrates to be alive and does anything to fulfill it´s life purpose (or coming closer to an understanding what this could possibly be) and by that being of great value for yourself, for the people around you and even for mankind and human evolution in general.

Some simple rituals that make you feel happy

Let me add some ideas for oxytocin: Have a purring cat around you. Have skin contact with people you love. Go for conscious slow sex.

Serotonin: All kind of workouts. Sweat in a sauna. Have a hot bath. Cold exposure works also. Expose yourself to beautiful art you like. Listen to your favorite music.

Dopamine: Set yourself goals and go for them. Notice what you have achived already. Sense that you are on a good trajectory. Reward yourself with something you enjoy.

Endorphine: Smile. Gift something to someone you like, maybe just your time and attention. Expose yourself to pleasant situations.

How do drugs affect neurotransmitters?

First of all I don´t encourage you to experiment with illegalized substances. But I neigther discourage you to run conscious experiments. It should be obvious that none substance should be taken on a regulare base. But as a corrective experience it can be quite powerful – giving your body and brain the chance to remember different states of consciousness and being. This remembering might enable you to access the same states later without the support of supplements / nootropics / medicine / drugs. At the end it is all about consciousness and clear intention. This is where the real magic happens, biochemical support is just one of many possible tools.

That being said lets jump to the most popular substances and have a look what they do to the brain.

The most common (serotonergic) psychedelics work by a method of action strongly tied to the neurotransmitter serotonin. The tryptamine psychedelics, such as DMT and psilocybin, structurally resemble serotonin itself.

The phenethylamine psychedelics on the other hand, such as mescaline, more closely resemble the neurotransmitter dopamine.

MDMA affects the brain by increasing the activity of at least three neurotransmitters: serotonin, dopamine and norepinephrine.

Cocaine acts by binding to the dopamine transporter, blocking the removal of dopamine from the synapse. Dopamine then accumulates in the synapse to produce an amplified signal to the receiving neurons. This is what causes the euphoria commonly experienced immediately after taking it.

Caffeine interacts with the dopaminergic system. Glutamatergic receptors have been found to be involved on the neurobiological effects of caffeine. Additionally, caffeine has been found to suppress the inhibitory (GABAergic) activity and modulate GABA receptors.

Nicotine binds to nicotinic receptors in the brain, augmenting the release of numerous neurotransmitters, including dopamine, serotonin, norepinephrine, acetylcholine, gamma-aminobutyric acid, and glutamate.

Why is cacao so good?

You all like chocolate and cacao, don´t you? ❤️ Me too! The state of mind and the bodyfeeling after it is so nice. So why is that?
The main psychoactive components in cacao are L-Tryptophan and Theobromine. Tryptopan is in the body transformed to Serotonin. That´s what makes you feel well and happy. It regulates your emotions, your motivation, your pain tolerance and your mood to name just a few.
Theobromin acts similar like caffein – it is stimulating, raises your heartbeat and gets you alert and focussed on the here and now.
Welcome to neurohacking. With this knowledge you can drop your chocolate addiction and go for raw cacao (without shitty industrial sugar) or directly for Tryptophan or 5-HTP to get the same effect without poisoning yourself. You are welcome! More to follow.
