Hello. My doctor has perscribed Nuvigil for me because I need help starting my day. I feel "dazed" in the mornings. It has gotten so bad that I don't dare try to drive in the morning, I've been in a few small accidents, just fender benders, no one injured thank God. I know I have sleep apnea, I've had it for some time now. I haven't taken the sleep test but I have the other symptoms, breathing stops, gasping for air while sleeping, this my wife tells me.
