I have been on Lexapro for 10 years with success and this summer I went through throat cancer treatments when the depression and anxiety returned. My therapist said that the Lexapro may not be working anymore and agreed that adding Wellbutrin may help. I am also on Ativan 1 to 1 1/2 mg per day. I have taken the Wellbutrin for two days and I have tremors and some loss of appetite. I am thinking of stopping it but don't know which way to turn.
