I heard about this stuff and know some pilots that take it to stay more alert and they tell me it works.From what I hear though its more of a smart drug than a amphetamine. Probably better off with 200 mg caffeine before working out but I'd be interested in what others who have tried provigil have to say. Was thinking about trying some. I don't think it's scheduled in the USA or if it is it's not very tight, its easy to get.
