Glucophage can definitely cause some stomach upset. If you eat carbs with it, it can get worse. I have been taking it for a couple of months now and it was about 2 weeks of feeling rather under the weather.
Since then, only when I indulge in carbs. It also took about 5 weeks to start really helping. They say every time you get an increase you can get the tummy problems again.
Your numbers sound great to me, what type and how long have you been diabetic?
Welcome to the forums, you have found a great place for valuable information, great people and lots of help and friendly atmosphere.
Hope to hear more from you soon,
Cass
