@danae25 asked, "Were you able to reduce your dosage of Medformin?"

No, I started on 1000mg twice daily, I've experimented with cutting it back but it seems to cost a few blood glucose points, so I've stayed with the same.

It allows me to cheat a bit on diet and still keep the BG below 5.7.

Actually it's been a bit of a struggle recently, my next reading might be 5.8 or even a little higher, but I'm working on it.
