Acetyl-l-carnitine might be a better example than caffeine. Caffeine is a good example of how you get some beneficial effects (alertness) with drawbacks (more reactive, straight thinking).

We'll see what my research turns up on the effects, I guess this is a likely drawback at least partially.

And also, drugs that are beneficial under certain circumstances or in certain combinations. I think this is a likely situation.

True. There are some studies that point out individual differences, but most are directed towards getting the mean to increase rather than the abilities of those who react. This is likely because most medical studies are directed towards finding pharmaceuticals that work for everyone; we have not yet reached the level where individually customized medications are practical/affordable.
A very interesting and clear posting.
