Had been on metformin and glybride and tajenta but my kidneys are compromised and function was going down.I've had none of the side affects other users mention. Does that mean it isn't working? Morning numbers are at 350+ and 2 hours after supper at 450-475 range. I have lost about 10 lb. Am I been too paranoid about the numbers. Next appointment with doctor is in two weeks. Should I wait or call for an earlier appointment?
