Like "There have been a lot of posts that have included reactions to Metformin. Try typing that into the discussion search area and you may find some answers. Some questions to consider. Are you taking it once or twice a day? Are you taking it with food? Have you tried breaking the pill in half and taking the 2nd half about 4 to 6 hours later? Your #'s are real good. If they are your #'s without Metformin, I wonder why your doctor RX'ed it for you. If I could buy those numbers from you, I would. My suspicion is that you had a stomach virus and it had nothing to do with the meds, but I would still like to know why he has you on Metformin with numbers that good."
