Hi.

I just started taking Metformin 4 days ago. My Dr. started me out on 500 mg. I seem to be doing rather well, except I have been a bit gasy (but that another story.) How do I know if I am getting enough Metformin in my system?
I see others on this forum that are taking 1000-2000mg. Why were your doses increased?
I just want to make sure I am taking the correct amount.
