I liked Provigil & wouldnt have been able to function during the day without it when I was on Fentayl for pain. It made me so sleepy& fatigued. But I got used to it & needed a higher dose & its very expensive & then I changed pain meds thats for now not as sedating so I am trying to go without it. I also am lucky enough to at least have drug induced sleep. I take a low dose of Geodon at night to sleep. Its a life saver. If I dont take it I dont sleep. Recently it started not working or if I flare too much it wont work well. So the next rescription I fill will be increased a little. I build a tolerance to my meds something awful. It seems to take 6 monthes to 18 monthes depending on the med. I have another friend who takes serequel. Which is Geodons equivalant to sleep & its helped her too. Its something to consider talking to your doctors about. Especially if you have any depression problems.
