bipolar disorde
"I've been on this drug since the US release date, previous to that having to cross the border into Mexico to buy Provigil. Luckily I have no insurance hiccups with Nuvigil besides yearly prior authorizations. I have sleep apnea to which I've had 5 surgeries to correct & am Bipolar 1. I take 2 x 250 mg. tablets daily, spaced by 5 hours--it really helps with the extreme lethargy you get from atypicals & mood stabalizers, I don't think I'd be able to hold a job without it. This is not some miracle Limitless drug for those who seriously need it, its a way to change your life to keep up when all your other meds just slow you down. I was on 1 dose a day & it wore off within 5-6 hours, thus the second dose. $5 copay with coupon on their site."
