I took Ambien several years ago. It made me sleepwalk and at night I would sometimes go into the kitchen and take everything out of the fridge and put it on the counter then go back to bed. Your mileage may vary.
One thing that did work for me was taking a Melatonin supplement. 1 mg was ok, but I needed 5mg. Melatonin is a precursor to Seratonin, which your body converts it to. Seratonin is a chemical that relaxes the brain, and it can make you tired.
You can get it at pretty much any store.
