"prescribed 7.5 mg (half a 15 mg pill) at night for sleep. first night i accidentally  took a whole 15 mg dose when i was supposed to take a half a pill. experienced some shortness of breath at first and felt what i can best describe as being drunk for the next two days off that single dose. stumbling and dizzy with a tiredness i have never felt i my life. it did what it promised and knocked me out, but for two days in a row. i realized i took the whole dose but was nervous to try it again. after 3 weeks of bad sleep i tried it again at the prescribed 7.50 mg and was much better. it does take time to adjust. i am now on week 4 and for the most part sleeping through the night. i did gain 7 lbs though, induces a  crazy appetite."
