I was put on insulin 2 years ago without being told, while in hospital for something quite different. When I got out, GP after a lot of tense discussion (I refused to continue the insulin) agreed to putting me on metformin. I found this forum, researched and learned a lot, went straight onto keto, BG lowered quickly and I started to phase out the metformin dose slowly and carefully. I was totally off the metformin after about 3 months. These days I am in the non-diabetic range, still keto with occasional forays into VeryLowCarb, 4 clothes sizes smaller as a very welcome side-effect, and happy to eat like this for the rest of my life. So it can be done, isn't all that difficult, but is only one way of handling this illness. Others prefer to continue with meds and have a wider diet. Some of us need extra help from meds. That's okay. We are all different.
