I'm 19 and I've been taking Unisoms for about a year now..I take three 50 mg each night. I can fall asleep without them, I just wake up easily. I find myself more refreshed in the morning and able to wakeup when I do take Unisoms the night before. I don't really like going to the doctors, and i'm a college student so I really can't afford a prescription drug; I also don't consider myself an insomniac. I'm just wondering if my body will be harmed in any way from taking them nightly. Thanks.
