My husband has had sleep problems since he was a teenager and it only seems to be worse now. He takes Zolpidem (not every night) and times it might help but other nights it doesn't work at all. I have now realized that this has effected his daytime activities. I can not let my guard down while he is driving a car or the motorcycle. He has severe issues of being able to stay awake doing those things. Once,he found himself in a place that he had no idea how he got there. I was not with him at that time, but it sure concerned him. Caffiene does not eliminate the problem. I need help or advice as to what we should do. Please supply any recommendations. We live in Texas near Ft.Worth. Awaiting a quick reply. I am concerned about getting in a vehicle with him. Zolpem, as I sai, works sometimes but it makes him a little crazy and it takes hours to work. Please help us
