unless i'm mistaken Sonata is much weaker than Ambien. IIRC, from the commercials way back when, Sonata is mainly for people who have trouble falling asleep, not staying asleep. It wears off much quicker, so there's nowhere near as much chance of grogginess in the morning. I know that the one time I had a script for sonata it might as well have been sugar-pills because they did absolutely nothing. I'd look for something besides this one if it were me. Personally, i've found that 10mg of valium + 3mg of melatonin about 30-45 minutes before bedtime works pretty well..

Good luck,
