I took two Ambien last night at about 11:30, hoping to be asleep by 12-12:30. I finally fell asleep around 4 a.m., and only after taking two Benadryl for allergies. I slept pretty soundly, though, and didn't wake up until 1:45 this afternoon. Apparently the pills will keep me asleep, they just don't help me fall asleep. So I guess I'll have to start taking them around 6 p.m. in order to get enough rest each tonight. Today I still feel tired but I don't feel as loopy or crazy as I have for the past few weeks. Apparently 10 hours of straight sleep was what I needed.
