Curious to hear what medication the other reprobates on this site use to maintain their high levels of attainment, day-in, day-out.
I myself take two 50mg pills of promethazine before bed: I find it helps me get to sleep and isn't so strong that I'm hugely groggy the next morning (although I do sometimes wake up a little cloudy minded).
At uni, I used to take a 20mg dose of Adderall during revision season in order to help me put in the hours. Nothing out of the ordinary there, I'm sure. I'm yet to dabble for work.
Recreationally, a lot of the guys I work with (traders) partake in the ol' Columbian marching powder. I also know one trader who likes to light up the ganja after a night out to help de-stress before bed.
