The thing that I don't get is the A1c of 6.5% is OK, when "normal" people have one of 4.5-5.5%. I do think it is a "low blood sugar will kill you in an hour or two, and high blood sugar will kill you in 20-30 years" thing. Does my blood sugar go above 200? Yes. However, with the CGM, I take immediate action to get it back down. Do I go low? Yes. I carry glucose pills to mitigate it.
