"i was afraid to try this due to some bad reviews.i was getting so depressed staying awake all night and sleeping when the world was living. i tried 10mg with no effect but 20 mg is such a blessing. i fell asleep within an hour and had a restful sleep with no peculiar dreaming. i awoke with no grogginess and all perky and ready to go! i got 10 tabs of 10mg with a voucher and am getting 20 mg with a voucher. after that-i hope my doctor can work with humana to get the medication at a decent cost. i am 72 and don&#039;t have to get up for work-i am sad for all you insomniacs who have to rise and shine for all your obligations. i am praying for you."
