A few years ago I talked to my doctor about anxiety and he prescribed Lexapro. Last year he wanted me to stop taking it because I felt better. So I did around November. Things were ok at first (after the brain zaps stopped) but the last few months have been hell. The last few weeks I've had this sick nauseous feeling in my stomach every day and a terrible taste in my mouth and no appetite. I've lost 16lbs without trying in ~2 months. 

Went back to my doctor and he put me back on the lexapro. He also gave me something to help sleep while the Lexapro kicks in. It was Trazadone. First night I took it j was up vomiting all night. Same thing the second night at which point I stopped taking it. He gave me Ambien instead. Took that last night and slept only Ok (but the vomiting has stopped). 

I'm still nauseous though all the time. I cut the grass today and had to stop three times because my stomach feels like it's being tied into knots. Is this the anxiety or the trazadone? 

I feel helpless and sick all the time now. Need advice or pretty much any help.
