I mean, it's a question of personal neurochemistry.
I smoke pot and drink because that's what has helped me "wind down and go into this mode" (of creativity).
But when I drink too much caffeine, I find it hard to focus.
And meth was *amazing* (no; you don't understand), but it's nothing that ever made me not regret doing it, because the physical toll wasn't worth the high (as extreme as it may have been).
I feel like you're still asking drugs to give you some magical power, though... and that's just not how it works.
The only magic that's out there is already within you, and if there were any drug capable of tapping into it, it would already be available.
Drugs that make you lie to yourself aren't the ones you want to take, though.
I guess maybe your meth is my pot, though... like, again, it's a question of intrinsic neurochemical specificity that quickly approaches absurdity in terms of asking other people what drug you should take to get what you want.
The real question is what you want, OP.
