Thanks for your response! It's nice to know I'm not the only one
I have never had side effects (besides feeling a huge pill sit in my stomach) from Metformin or Glucophage. No diarrhea or anything... I actually like Glucophage better because it makes me less bloated (at least I think so).
How much are you taking? I am on 2000 total per day, two doses of 1000. I think there's a max you can take per day (like 2500) but maybe I'm wrong.
