I have been give reglan for the treatment of gastroparesis which is to help my stomach empty I have had diarrhea and I just need some people to please email me as to what I should be looking for with this drug. My first doctor would not put me on it because I suffer with depression but after a couple stays in the hospital another doctor did put me on it so after reading and trying to find what to expect I am just not sure. I have to take the medicine of I have nausa and vomiting all the time what othe choices are there?
