Had total knee replacement surgery 5 weeks ago. Only getting 1-2 hours sleep nightly(get about 2 or 2 1/2 hours sleep if I take the pain pills, oxycodone, 5 mg, 2 every 4 hours). So primary care physician prescribed Trazodone, 50 mg, 1-2 night. I tried 2 last night, got about an hour and 10 minutes sleep, woke up with a terribly stuffed up nose, unable to breathe, so was awake rest of the night. That stuffy nose feeling is still with me the next day. Should I try taking just 1 pill tonight and see what happens? I am so in need of a good nights sleep. I was hoping to stop taking the pain pills, was hoping the trazodone would let me do that. Any ideas???
