then perhaps consider the original chill-pill, propranolol. it's not habit-forming like benzos, and is particularly effective when one must perform or speak in front of people.
keep in mind, the racetams affect people differently, obviously. they are most noticeable when you're in a mental funk, caused by excessive drinking, pot-smoking, or what have you.
I'm not a fan of dopamine reuptake inhibitors, which adderall, ritalin, and cocaine are. the crash isn't worth it, imo; big pharma and industry favor such compounds because productivity is the bottom line. the repercussions are drastic changes in mood.
I favor racetams because of their low toxicity; in particular, the AMPAkines, such as CX717 and the like, show real promise, and I hope research continues with this novel class. the AMPA-glutamate receptors are directly correlated to learning and cognition.
