Drugs to build up that mental muscle

I don't know what effect neurotransmitter precursors have on endogenous production, which is why that information would be useful so we can better judge their safety. The steroid example was to point out that there could be substantial repercussions from taking a substance which you produce naturally. You don't even have to take excessive doses -- take in only as much as you would normally make and your body's production may drop to zero, since it's now being completely replaced. Steroids must be cycled down gradually, because going off cold turkey just leaves you with a crashed endocrine system. If neurotransmitter replacement works similarly, one can imagine a few problems that might crop up with a crashed brain.

> Choline precursors don't seem to have these same "down-regulation" harmful side effects when taken in moderation to bring brain acetylcholine levels back into "normal range."

"Don't seem"? Human studies needed. Maybe these already exist -- that would be handy. I'm not familiar with neurotransmitter supplementation.

Taking something because you have a deficit is indeed different from trying to massively exceed your nominal levels.

In the context of performance-enhancing mental drugs, exceeding your typical levels is of course the point of the exercise.

> "programmer burnout" which likely involved depleted acetylcholine levels in the brain

Possibly, but that assumption seems like it could be quite a leap.

Kind of like saying coffee works because of depleted caffeine levels in the brain. In fact, we have no data on what caused his particular case of "burnout". We can well imagine that an adrenaline shot, cocaine, ephedrine, and many other drugs could well "restore performance", but that doesn't indicate there was a deficit of those particular substances.

Provigil and Ritalin may also help but that doesn't mean there was a deficit of those, either.

An ACh deficit is only one of a bazillion possible reasons for "burnout".

There have been a number of studies done with choline supplements in a variety forms. Here is a list of citations

None of these listed have found the rebound side effects. I am not saying that you couldn't cause yourself problems at a high enough dosage, but in the dosages used in the studies it's not mentioned as a side effect.

This is not true for acetylcholinterase inhibitors (things like huperzine, arricept, galantamine,...) which can cause a significant excess of acetylcholine because they inhibit the down regulation process.

You are correct that I was speculating what might cause "programmer burnout." I agree with you that there are people who believe in "mental performance enhancing drugs" but I am not one of them. I do think that folks with ADD may be able to take substances that limit their ADD and I think that you can take things as you age to limit the effect of age related cognitive decline, but I don't think you can "supercharge" someone in their teens or twenties.

One of the great discoveries of the last decade has been that we continue to add new brain cells (at a much lower rate than in early childhood) all of our lives and that lifelong learning and stimulation does in fact encourage the formation of new connections and delay the onset of diseases like Alzheimers.

Our brains are plastic and respond to how they are used. In that sense my answer to the original question of "how to build mental muscles" is: I don't know of any drugs but I do believe that mental exercise helps.
