Me - being me - from the moment I was diagnosed I went back to low carb eating, and I ordered a large amount of meat at the butcher on the way home. That evening I ate meat, next day I had a carbless first meal and then a bit of salad with the meat, next day I had fish, I think - with a little salad, and went on from there.
I did try to take the tablets, but I was so ill, so I gave up on them and just went on eating low carb.
I suppose that if nurses or doctors said 'oh this might make you incontinent, so you need to buy a professional quality carpet cleaner and sped three or four days at a time no more than twenty feet from a toilet.' they might not get many people to take Metformin. Yes, some people can take them and be absolutely fine but I wish they'd be a bit more open about the possible consequences.
Low carb foods are far more interesting than the high starch and sugar ones, I think. I have beef, pork, fish, hogget (well grown lamb) and find them all delicious, the idea of no more potato or rice really doesn't fill me with any sort of regret.
