As a side-note, I also was put on birth control which helped tremendously with my cycles and irritability.
My doctor upped my dose of <span style = 'background-color: #dae8f4'>metformin</span>
about 4 months ago. I take two 750 mg <span style = 'background-color: #dae8f4'>slow</span>
capsules a day (1500 mg total--3x my original dosage per day). Yesterday, after dinner, I had some chocolate (I should not have, I had several pieces, but not a truck-load or anything...was not anticipating anything bad coming from it). I woke up at about 3 am with severe upper and mid-abdominal pains.
