No - I stopped taking the Metformin and statin after about 5 weeks - my quality of life was such that if I continued I'd have been suicidal.
I went to do the Christmas shopping and could not remember where I'd parked the car, and when I opened the back I found I had already done the shopping - we were eating sprouts till February.
The side effects have reduced but not gone away. I can laugh now when it takes three goes to get a plate out of the cupboard but am rather sad when I forget that my daughter was expecting me to visit her.
