Trazodone Hydrochloride and hangover

I was given a prescription for Trazodone four days ago beginning with a 150mg dose. I have a very long history of getting by on three to four hours of sleep and was constantly tired. That first dose really knocked me for a loop the next morning. When I first stood up after the alarm went off I was spacey, groggy, unsteady on my feet, joint pain in my knees and hips, and slight pain in the muscles of my legs. It was a full three hours before I felt somewhat better although I felt unsteady on my feet and when I walked, I walked as though I had a hangover. I decided to only take 75mg tab the second night. I slept twelve hours. When I awoke the above mentioned symptoms were still there but were much, much lest in intensity. The third night I took 50 mg. I slept nine hours and when I awoke the symptom were really minimal and felt quite normal after an hour or so.
