I was excercisin religiously
and watching my carb intake.i was eating
between 100 to 150gms of carbs. I was not on a ketogenic diet. After that visit i have been extremely ill. Nausea, vomiting, diarrhea. 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.
