I started taking Metformin, 3 times a day on Friday. I'm taking it with food each time. I've been extremely nauseous so much I can barely move sometimes. I've also been having (TMI) an overabundance of watery diarrhea twice a day. This has been going on for 4 days now. So far this morning I've only been slightly nauseous, so I'm hoping maybe the side effects have passed. Does anyone have personal experience with this problem or know how long this is gonna last? Do I need to call my Dr?
