I was aware that diarrhea came with this medicine, but I'm having issues of going 5-6 times an hour and vomitting. This has happend to me 3 times in 1 1/2 months. The doctor said I should not be vomitting so they took me off the Metformin for 2 weeks, did blood tests which showed signs of pancreatitis. When they did the scan, it came back negative for pancreatitis so, I was told I had "a virus". She put me right back on the Metformin and it started up again today. I'm very frustrated and don't know what to think.
