I just could not live with Metformin - for about 5 weeks I was only taking one a day, on two days I did take two but they were very bad days.
I stopped taking the nasty stuff and have stuck to low carb eating with enthusiasm close to desperation - if I had not got normal results in a year, I told myself I would have to start the tablets again. I have got to just about everything normal in 6 months.
All I got out of five weeks of Metformin was a professional quality carpet cleaner.
