I have a family history of diabetes (father was T1, mother was T2 diet controlled). I have been having problems with extreme tiredness & blurry/double vision after high carb meals (pasta, potatoes, breads) but I have no problems with 1/4 cup of sugar in a 22oz cup of coffee in the am. My doctor said I may be pre-diabetic & to start testing especially at times when I don't feel right. I feel "off" at anything over 110, at 140 I'm asleep. Is it normal for me to feel off at "normal" levels?
