I tried remeron for sleep only for a couple of days. I used to be a pharmacy tech and the drowsiness should go away. But the remeron made me suicidal so I went off of it. My dr then put me on seroquel, That was better for me. If the drowsiness doesn't subside call your dr and let him know. I know with the seroquel I was so tired for a while I was falling asleep in the bathroom at work. No kidding. But that eventually wore off.
