Acetaminophen / diphenhydramine
"I really like this pill besides the fact that I sleep all day. I take the pill every few days at about 12, when I'm not tired and 15 minutes later I become drowsy. About 30 minutes after that, I'm asleep. but I tend to sleep really late. I don't hear my alarms and I can't get myself out of bed. If you do take this I would consider taking it earlier than you normally would. Other then that this pill is the best I have found and works great just like it says."
