Bipolar Disorde
"I&#039;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&#039;ve had 5 surgeries to correct &amp; 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 &amp; mood stabalizers, I don&#039;t think I&#039;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 &amp; it wore off within 5-6 hours, thus the second dose. $5 copay with coupon on their site."
