Hello...
My experience (sp) with Metformin has taught me that if I eat too many carbs, my body will reject them via one end or the other. I take Anti-diarrhea meds like the one from Walgreens or the liquid form of the Immodium AD and it really helps the diarrhea.
I can really relate with the diarrhea, as when I first started Metformin I had diarrhea everyday for the first 6 to 7 weeks, and then once that stopped, I got to noticing that if I had too many carbs in a meal that I would get diarrhea, and have to take the AD med.
My doctor and I discussed it and as long as I don't eat anything that is too greasy, or over my carb amount I am fine and have been taking the Metformin for a little over 9 months now. Wow... has it been that long since I found out I was a diabetic, seems like longer and sometimes seems like only yesterday that I found out.
I hope this will help you a little.
Huggles...
