favorite because you got things done on it you mean ?Provigil would be my answer if it were on the list, but dexedrine instant release is my answer, because its duration isn't too short like coke, but not too long like meth.
I'm surprised mountain dew isn't on the list!
I'm also a fan of piracetam.
I would LOOOOVE to try 4-methylaminorex... it sounds lovely *drool* ... it sounds like a good thing to speedball with oxy...
you cant really get euphoria from modafinil imo
