I have been on Metformin since diagnosed in September last year, I have found that my taste has altered considerably, with foods I enjoyed before making me feel quite nauseous. I have brought my HbA1c down from 113 to 78, but my GP wants me to get down further and has increased my Metformin to 1,000 mg a day. This has reduced my appetite even further and I now have even less taste for food. has anyone else had this problem.
