I was on 150mg of Nuvigil but although it was working it was fully working, and I am on Strattera because my doctor wanted to see if the nuvigil full worked before she pulled my Strattera, so she upped it to 250 ever since she upped it not only does not work at all but I feel very nausea. Can someone please tell me whats going on! FYI I can't take stimulants do to my addiction history with stimulants. Does anyone know why Nuvigil stopped working? and what others suggested for wakefulness oh yes I should mention I can't take provigil either because my health insurance will not pay for it. Please, please help give me advice or info on these concerns it would be very much appreciated!
