i too am on Wellbutrin but im also on Lexapro. the lexapro was for depression and anxiety, the Wellbutrin is supposed to help wih my concentration. i was ok at 10mg on lexapro for a few weeks then became extrememly SUI. pdoc upped to 20mg and i didnt feel SUI anymore but extremely tired and hard to focus. then she added the Wellbutrin 100mg, she just upped that to 150mg but i havent started yet. she wanted me to finsih the 100 first.i would like to stabilize but life is just really hitting me hard these last few months and i cant get that grip i need.
