Nuvigil
"I am on Nuvigil now and have been for several months. I take the 250mg tabs. Before Nuvigil, I took Provigil for over a year and my doctor told me that Nuvigil was a new refined version of Provigil. They work great for a while, then your body gets used to it; I will go a day or two without it and it seems to work better that way. My insurance did not want to pay for Provigil, so my doctor wrote a letter that it was imperative for my quality of life, so they started paying. When I switched to Nuvigil, nothing was ever said about it. It does make me more alert, but I can still lay down and take a nap while taking it. It is sure better than nothing, Or I would be in bed 24/7 as before."
