Hi. It's total guesswork. GPs just increase the dose in the sometimes vain hope it will finally do something. Metformin never does much but does help and I still take it. If you have any problems with it insist the GP changes the script to Metformin SR (Slow Release) or possibly refuse it if the GP won't change the script. Diet as ever is the number one action for T2 and other tablets/insulin for T1.
