blood sugar dropping rapidly when after exercise. My
doctor said it could be the
phentermine but that the metformin xr could also be reacting to the phentermine. I stoped the metformin, felt better then my sugar started going up. I started the metformin at half the dosage since i am 13lbs lighter on friday night, today i am in severe abdominal pain, belching, horrible gas, nauseous, and vomiting which smells very acidic. Could this be too much ketones, or the medicine?
