I don't know about you guys, but any kind of adderall/concerta/dexyadrine etc etc.. makes me feel in the zone, the thought process in my head heightens the clarity... not that I can't clearly think without it but it certainly helps my game, and I think its +EV moreso in a tournament due to the long grind and helps me not get bored easily. but....

still havnt tried adderall yet... but i have been experimenting with Alpha Brain, a nootropic, for about the past 3 weeks

from my personal experience so far, i dont think its worth the money (its pretty damn expensive), but it does help my poker somewhat... i've notice that i am able to think more clearly and faster but it only lasts for bout 1-2 hours, so i usually only take it when im in a critical point of a few tournaments or in the FT

unless u make alot of money and dont mind spending $100 on a 3 month supply of pills, prob not worth it

Beyond some caffeine, why on earth would you need drugs of any sort for poker?

Self-discipline seems a lot cheaper and healthier.

because self-discipline is more difficult for some people.
