I suffer from gastroperesis and I found that it was my antidepressant Effexor/venflaxin was the problem. So I was weaned off by my dr. of it and I’m so much better. I couldn’t eat, lost 30 lbs, vomiting daily. I can eat small meals now, stomach still blists and I have back and abdominal pain but nothing like before getting of Effexor. I am 100% better than I was. Please look into it, but do not come off meds without talking to Dr. first.
