Benadryl. It's not really a drug, and it works without making me feel like crap the next day. I take it about 3 nights a week. It makes me drowsy & keeps me asleep once I get there. Are you on PT or chatting into the night?

Most people buy Tylenol PM’s and take those, but the ingredient in it that makes you sleepy is dyphenhydramine (sp?), which is the same thing as Benadryl.
