insomnia
"I have a friend who had taken ambien for years without any problems. For whatever reason he had an episode where he took his pill and then remembers nothing until he was at the police station. He had drank three beers (which he only knows because that's all that was in his frig) then proceded to drive (!!) and ended up crashing into another parked car. This is scarey stuff, eh? It works wonderfully, but I surely wouldn't want to have a blackout and end up driving. Is there any class action suit against this drug? I've heard of the other stories -- walking naked in the winter cold, eating while sleeping, and then my friend's experience."
