I started taking Wellbutrin a couple of weeks ago and started feeling so much better! I still wasnt sleeping though so my Doctor put me on Trazodone. I am taking 100mg at bedtime. Since I have been on the Trazodone for about a week I have noticed that Im not feeling so good anymore. I went from having energy and being happy to no energy and not so happy. The Trazodone does help me sleep! : ) My question is..How long does Trazodone stay in your system and could the Trazodone be causeing my sudden change?
