Yes, I have noticed being cold/feeling the cold more in the last 5 years; but in have also lost about 100 pounds. Also it started back before the weight lose when I was put on metformin; do not know w\how it works but I am not the only one who has felt that the Metformin has caused cold intolerance. In that I have been off the metformin for two years I do not think that it is the cause currently which leave less fat to insolate or age!
