"i was put on doxepin 10mg, for wake up middle of night insomnia. every time i&#039;ve taken it( about 5), i&#039;m knocked out and sleep heavy for about 9 hrs. then i&#039;m very groggy the next day and sleep off and on. the feeling rested and like i actually slept is great. but, it&#039;s almost too good. i&#039;m going to ask my dr. to reduce to like 3mg."
