Is it possible that this buildup in medication has happened to me? I've been taking 10mg of lexapro for the past 2 1/2 months, and 100mg Trazadone at night, and now 100mg wellbutrinSR 2X daily for the past month. And after a little while I was feeling a little more peace and enthusiam, but recently my depression symptoms, crying, sadness, lack of motivation etc. have returned. I'm seeing my Dr. tomorrow, but has anyone else had this experience?
