Has anyone had terrible upset stomachs while on Metformin? I am on my 4th day and the pain is so bad at times that I can’t sleep, or even sit/lay comfortably. For two or so hours after each pill I have to be near a toilet (sorry if it is TMI). Just curious if anyone else is having these symptoms and if they went away after time? I am taking the medicine with full meals every time but that has not made it any better. Also drinking a lot more water than usual. Thank you!
