insomnia
"I have been taking Trazodone for over 10 years, I started on 100mg and went down to 50 when I tried it and found that it worked just as well. I never used to sleep at night, with trazodone I consistently sleep through and have never had to increase the dose. I stopped taking it for a few months and was ok but went back on it when I started waking up in the middle of the night. I haven't noticed any side effects, my allergies do seem to be worse at night so maybe the trazodone affects them but when my allergies are not bad I don't have any sinus problems with trazodone, I also take zyrtec at night for allergies"
