I am so sorry for your loss. Anxiety and stress certainly don't help our gastro. system. I took metformin for 8 years and had horrible gastro. symptoms. My dr. diagnosed me with IBS and it was really bad. After diet change, got off of metformin and all my symptoms went away. It was wonderful. Stayed off for 2 years, but had a bad virus which attacked my organs. Blood sugar and pressure went sky high. They put me back on metformin and my stomach bloated up like I was ready to deliver a baby. Nauseated, diarrhea and same symptoms I had before. Got off of it... Tried trulicity and was horribly sick for a week until it wore off. It gave me same symptoms as metformin. Waiting for my dr. appointment to come up....
