I was on trazodone for a very long time, for falling asleep. I would sleep until 11 AM and sometimes later. I just couldn't shake that "hangover" feeling, but I thought it was just me being lazy or depressed. Then, I realized how dizzy I was when I tried to get up in the middle of the night, so I went off of it. I've felt a whole lot better ever since. I can't remember whether or not I was on the extended release.
