I actually had it happen at the er one night. Had gone in for a severe headache turned out it was sinus infection and I asked to have sugar checked because I just didn't feel right not really anything I could pinpoint tho. When they checked it was at 40 and they freaked out guess they aren't used to seeing that...........hehehe. Told my dr about it and boy they got a class on it he took over the er the next week after seeing me.........hehehe.
Guess it goes to show don't have to have this for 20 yrs to have this problem I've had it for 14 yrs now and have had the problem of no warning signs for almost 2 yrs now.
