I have come up with a solid theory, based on my indepth understanding of the mind, to why I believe there is no such thing as a tolerance in Nootropics. I will explain the true reason behind people thinking there is a tolerance.
Many people don't realize the power of intention, when it comes to the mind. Simply, consciously intending to do something before you do it can boost the entire outcome of the scenario.
Here is why I say there is no such thing as a Tolerance in Nootropics.
I will use Pramiracetam as the example, I will also cite another example of another related boosting substance and my experience with it.
Pramiracetam essentially boost Acetylcholine levels and this builds over time. People begin to experience really good recall and learning. Though after some time they notice the effects are 'not so much'. They call this tolerance.
I disagree. Here's why. When your memory boost like that, memory recall becomes much easier. When memory recall becomes easier, the mental effort to retrieve a memory also becomes less. Resulting in an experience that your memory benefits aren't getting any better. When REALLY, the mental effort your mind used to put forth to retrieve a memory has greatly decreased, giving you the feeling that you're not really getting a boost from it.
If the mental effort is consciously practiced and worked on, then you will notice there is ALWAYS a boost. The easier it gets to recall memories the less concentrated attention is required to recall a memory... this can result in a gradual disconnect in conscious concentration depth because it requires far less concentration power to retrieve memories. As your memory gets stronger and stronger, your mind gets used to not having to concentrate as much to recall memories. This adapted habit of not having to concentrate as much then results in a disappearance of the original phenomenon of intense memory experiences. Your mind grows so used to such an easy recall of memories. Meaning if you do not intently focus your attention and concentration(as in meditation), then your ability to concentrate rapidly on a deep level will dwindle because it is not being used as much since memory recall is simply easier.
The more will power that is put forth to a certain task(such as memory retrieval), the more you will get out of the faculties concerning that. Meaning if your will power remains stactic and you train it over time, along with the memory faculty boost, you will continue to experience enormas growths in memory abilities, endlessly.
If you don't train your willpower/concentration, then it will grow weaker while your memory faculty grows stronger. There is a direct correlation between mental exertion and the vastness of memory faculties in regards to the 'wow' moments you get on a nootropic.
Here is a graph demonstrating what happens the longer you are on a nootropic. Your mental faculties grow but the nessisary mental exertion required weakens as not much mental effort is needed to perform the task you frequently perform due to the larger mental faculty... Though it will not weaken if you train it.
Here is both graphs combined pointing out where the 'tolerance' effect happens and why.
Understand? On the other hand, if one intently practices his concentration and focus, holding it deeply on a memory, even after it has easily been retrieved, the more he develops his willpower/concentration power, the longer you will experience the amazing phenomenon associated with Nootropics.
Now with this said. This concept applies to ANYTHING that boost the mind in any way. REMEMBER THIS. If you do anything that makes a certain task or ability easier for the mind, then you are inturn weakening the faculty that exerted effort to do that task before. If you do not continue to practice and exert that faculty beyond the necessarily point(while on the substance), than you will experience it weakening.
The bad thing is, this can result in, once you are off the substance, and your mind slowly loses(over 5-6 months) that incredible boost that it has built up, your concentration, or your exertion/will power will remain weak, and you will actually be mentally WEAKER than before when you started the stack/substance. You lived so long with that substance in your system making things such as memory retrieval easy for you, that it weakened your will power and needed effort.
I remember when I was in high school, I would take Vitamin B12 every day for energy, the sublingual kind with like 16,000% the nessisary dose. This was all dandy. But it eventually got to the point that on the days I didn't take it, I was drained to no end. This was a result of the b12 making 'action' so easy for me that my concentration/will powers dwindled, so when I didn't have it in my system, my concentration/will powers were not able to crank up enough juice because it grew so used to the b12 faciliting everything.
If you understand these concepts and practice activities that train your mental exertion, and constantly push your mind to the limit... you will continue to forever develop insane abilities as long as you continue to take the Nootropic.
For instance, Some buddhist monks live off of very poor diets, barley Rice and Water and Green Tea. Though because they meditate so much, their ability to 'mentally exert' a conscious effort becomes so strong that they can pull of extreme mental feats that the average person cannot, even only with an average developed mental faculty. This is because their will power is so strong that they can dive so indepth to the faculty. And the simple act of diving this indepth into a faculty alone will cause that faculty to expand and become stronger, so it is a win win situation.
Practice your mental effort and will power, and you will never experiences a tolerance. You will only experience gains. Do not get lost and distracted by the crazy mental feats and extreme easy of remembering things, if you let these distract you then your mind will get acustomed to not having to put forth much mental effort and your mental exertion abilities will weaken. When they weaken so will your ability to take full advantage of the developed mental faculty!
