Just signed up here and want to thank everyone for such good info provided. I'm Ron and I am a 57yr old Vietnam Vet that discovered 9 years after I was discharged that I was a type 1 diabetic. I learned after the fact that not only did agent orange do an excellent job as a defoliant, it also did an excellent job in destroying my pancreas as well. I will never complain tho, cuz I have buddies with strange cancers from exposure and all I have is diabetes. I spend a great deal of time at VA hospitals and it doesn't take long to realize there are people worse off. I love my MM722/CGMS. In spite of all the people that complain, I have had great results with some extremely accurate numbers(meter test vs cgms). Even tho that sensor needle tooks ominous, I have yet to feel much of anything. So far, I just switch from my left to right sides. My average sensor life is around 7-9 days. I'm betting the physiology of a person is the main reason some can only get 3 days and others may get 13 days. Thanks for allowing me to be a part of CWD. I hope I can helps others as I am helped by others.
