I was moved on to gliclazide, but maintained the 3000 mg metformin a day. My BS took a tumble straight away, I still get peaks above what I like and its now a question of identifying what's causing the peaks. I also get lows, these aare down to irregular meal patterns which I am tryin to work on.
they seem to have taken me off, as metformin has been removed from prescription. but I've spiked at 18!! and low at 4. also affecting sleep patterns. going to move to an almost 0 carb diet, but maintaining the fibre. and I do need to lose 3.5 stone.
