My experiences with Provigil 200 mg taken upon waking up - 18 months:
Purpose was to keep me awake as I was taking other anti-dep and anti-anxiety and high bp stuff - all of them in varying doses in the morning.... COULD NOT GET UP or stafy AWAKE! Provigil turned out to be my saving grace with one caveat (in a moment) and Provigil with Adderrall XR 50 mg was firing all of my 8 cylinders in harmony. The one caveat to any drug combination that I am highly sensitive to is the mandatory 8 hours of my beauty (delta) sleep. If that gets screwed up, the next day, I would rather be in twilight zone, sipping worm filled taqs/margeritas.
Now, I am on Concerta which does NOT have the punch/kick *** that Adderrall gave me. I turned into a pathetic little weasal that was disgusted at my self. Yes, I do take 54 Mg/max dosage and Yes, my shrink does NOT want to screw with increasing it. Anyway, the good thing that I experienced with Adderrall was the consistency of delivery of outcome/results. I mean you knew that once you popped the pill, n minutes later, cylinders would be firing and reached alll firing sequence soon. Concerta, is another story - do NOT want to bore or turn anyone off....will share it if requested....especially, because it also has to do with Paxil CR and libido performance.
