I take 100 of trazadone at bedtime, but around 8 am feel very anxious. How does trazadone help anxiety during the day if it only lasts 8-10 hours, and is out of my system by morning? I am experimenting with taking 50 in the pm and 50 in the am, but feel I tired and out of fuzzy during the day. My daytime anxiety is improving, but I find it hard to focus.
