Can't seem to get blood back to normal fasting blood yesterday were at my lowest 12.1mmol and today 20.1mmol I've reduced carbs nothing seems to work on metformin but that seems to do ****** all.
Metformin won't do very much. It helps to a very limited extent only. For the majority of us diet is the key to control. I see from your previous posts you have been struggling.
If you tell us what you eat and drink in a typical day we may be able to help.
