I am diabetic (possibly LADA, as I don't have either the type 1 or type 2 pattern). I only operate well in a quite narrow range (3.3 to 5.5, or about 60-100) and I feel better in that range too - so much so I can accurately my blood sugar readings as being in that range, below or above. My diabetes nurse, however, seems quite keen to get my readings above 5.5, preferably above 6. I would like to know if non-diabetics tend to have a "range" where they naturally sit, and if this is a possible explanation of why my body and brain keep telling me that's where they want me to be. What do you think?
