"first night on 10mg didn&#039;t fall asleep until 5:15 am after 4 am popcorn binge. woke up about 7:30 am. same on next 3 nights with middle-of-the night coffee-cake, chocolates and even a couple of frozen dinners. dr. upped  to 20mg. same result. hardly any sleep, night snacking, and started eating more during the day. people have commented about rapid weight gain. they&#039;re right. i gained 8 lbs. the first week! my weight has been pretty consistent by 2-3 lbs. for years. going back to ambien!"
