I m a diabetic, my body had not been digesting my 75 me extended release metformin. So the other day I started 500 regular release metformin. I also take 5 mg glipizide. but I got terrible diarea, and stomach gas, and headaches, and nausea. I decided not to take today and felt sooo much better. I took tonight and I m stating up all over again. Will this be going on for awhile cause I also got very cold,too. This is all staring again. Will this keep going on for awhile? Cause idk if I can keep feeling this bad?
