sedation
"My head spins with overactive thoughts at bedtime causing insomnia. Ambien worked, but changed to Trazadone 100mg. I fell asleep quickly, but woke up feeling dizzy, as if hungover. The feeling lasted throughout the day. I didn't  like the lingering feeling, so I halved the dose, 50 mgs. Same side affects, felt drowsy and dizzy in the morning. I will go back to using Benedryl, as it didn't give me the Zombie feeling like Trazadone. (Xanax worked for me, but I didn't want to get addicted to it, so I don't take it.)"
