I felt ill on Metformin and Atorvastatin - mental confusion was only a small part of it, but it frightened me a lot. I was eating low carb, and I have gone even lower now, to 40 gm of carbs a day. I do not need any medication and have to make my clothes smaller from time to time.
Low carb is how many people got rid of their type two diabetes symptoms, and are classed as in remission. It is the single most powerful, and most successful method of lowering blood glucose - so much so that you'd need to be very careful with the drugs you are taking or you could go too low.
It is entirely your choice, of course, but there is a lot of information available on the forum, and success stories from those who have got results even better then mine.
