I have found a very strange phenomena involving alcohol, which I have drunk far too much of for far too many years.
I was diagnosed 3 years ago and am now on 1 x 500mg metformin a day. But since starting the tablets, initially I was on a mix of Gliclazide and Metformin, I have lost 2.5 stone, my liver function tests, which used to be appalling, have returned to normal; my GP even congratulated me on stopping the booze, and was very surprised when I said don't be ridiculous, I drink at least half a bottle of wine and a large whisky every day.
He was most surprised by this, as according to the tests I had been alcohol free for about 6 months. Anyway I also attended a whisky tasting in our village, and the following day had a horrible hypo on the golf course. Fortunately was near the club house and got some fats acting carbs down me and stopped the shakes.
So don't let the booze take over and only one glass max, I just use a very large one.
