insomnia
"I started Ambien when Lunesta did not work for me, and it was effective in helping me sleep. One problem developed, I began getting up in the middle of the night and eating , especially if I thought of something before I dozed off (e.g. the chocolate cake I was saving til tomorrow, etc.).  I had to stop when I woke up with a cut on my hand, and realized I had cut up a leftover pork chop to eat. I had no recollection of eating, slicing my hand, or putting the bandage on. I cut down to half dose (5 mg) and the night eating stopped.  I wish I could find a substitute, but this really helps me sleep deeply and feel refreshed when I get up in the morning."
