"almost immediately i felt better. at 2-3 hours of sleep at night, i had a good 15 hours (along with 3mg of melatonin) of sleep the first night. a little groggy my 1st hour awake. two weeks in, i&#039;m up 3lbs, which i needed. love it. zoloft was the devil at 75mg/day. thankful to my doctor for prescribing it."
