insomnia
"I was taking regular Trazodone on and off for a couple of years, it stopped working so my doctor switched me to Desyrel. It's a good pill for the fact that it does make you tired, but I'd make sure you're gonna get 8 or more hours of sleep before you take it. I was prescribed 100mg pills, and I only took half of a pill whenever I took it, and I had the hardest time waking up the next day. Also, with the reg Trazodone and with Desyrel, it took a long time for it to kick in for me (2  hours), but that might be because I have a high tolerance to pills. If you're new to this medicine, take it on the weekend, or whenever you can sleep in, so you can see how it works."
