For serveral months I have had trouble with my digestive system. Almost everytime i eat I feel sick and often cannot keep food down. most of the time when I throw up, it feels like acid and burns. I feel weak most of the time. I ve been to med express a few times and they give me medicine that works , but when I dont take it, Im back to the same thing. I do work a full time job, under stress a lot, and am constantly on the move. I often feel as though I may be dehydrated.
