Paul Erdős famously claimed that amphetamines helped him in mathematics:
> After 1971 he also took amphetamines, despite the concern of his friends, one of whom (Ron Graham) bet him $500 that he could not stop taking the drug for a month.[34] Erdős won the bet, but complained that during his abstinence mathematics had been set back by a month: "Before, when I looked at a piece of blank paper my mind was filled with ideas. Now all I see is a blank piece of paper." After he won the bet, he promptly resumed his amphetamine use. - http://en.wikipedia.org/wiki/Paul_Erd%C5%91s
Erdos took amphetamines daily after his mother died in 1971, and claimed to sleep for about 4 hours a day while on amphetamines. He did not recommend them to anyone else, and he objected to the use of amphetamines being included in his biography because he didn't want to cause any kids to start taking drugs.
Erdos was also apparently more prolific after starting amphetamines, perhaps because he started sleeping significantly less.[1]
