"i have battled insomnia for most of my adult life. i was prescribed sleeping pills what a disaster. my dr. was hesitant to prescribe this medication as weight gain is a side effect. she prescribed 7.5 to 15 mg a night and my sleep has been sound for over 2 years now. i gained probably 5-7 pounds gradually then stopped gaining. i do exercise and eat well this helps with sleep also. sometimes i have daytime grogginess but usually not a problem. this medication was a god-send for me."
