Last night I took my first dose of Trazodone 100mg prescribed for insomnia. I read that dry mouth was a side effect and I have to say it absolutely was for me. Aside from the dry mouth, I had to get up FIVE times during the night to pee! I only took a sip of water each time I got up to try an relieve the extreme cotton-mouth. I felt like I had taken a diurectic. I had no other side effects. Has anyone else experienced this? As it stands now, it's useless as a sleep aid for me.
