I second this. Metformin is a good drug, but it can be overwhelmed.
I have switched to a zero carb diet — boy I miss the desserts and the bread and the beer.
But it has put my blood sugar levels back to normal and I am losing about two pounds a month. I do not miss the food I used to eat now, and just made it through Thanksgiving with no weight increase.
It is a big deal to not eat carbs (called the keto diet) you have to ask burgers to be wrapped in lettuce and give up the bun. BTW, bread is something bad for us that really adds taste to food so the soner you give up on it, the better for your life long health.
You can beat this with diet and exercise — but it takes personal desire to do this approach — but it works.
For hamburgers Use Portobello Mushrooms, grilled, for the bun...................
