I have been T2 since 1995 and on Metformin from 1996. I have recently been having problems with pain in my body, my GP has taken me off Metformin. The pains have largely subsided but my blood sugar levels are all over the place i.e from 13.7 down to 3.7 then upto 21.5 and this morning starting at 15. What alternative is there to Metformin
