Hi Peggy,
Firstly I totally agree with everything Chris says and secondly, if you are just in the early stages of impaired glucose tolerance, I am a little bit suprised at your doctor putting you straight on to Glucopharge. To me it sounds like the patient sits down and the doctor takes out his pen and goes "right ..Glucopharge...NEXT!!"
It seems to me with your self motivation and power to diet and excercise (and all power to you) that he would at least have discussed this a little more fully and encouraged you to try these other things first. Not that I am suggesting that there is anything wrong with the med but it does, in my experience, tempt you into letting slip, even though they do emphasize that it should be taken in conjunction with a diet.
I am not an expert on this so please, anyone who thinks what I am saying is nuts, please correct me.
Anyway keep up the good work with the diet and excercise and you will do well.
Mike
