Great numbers...I can match her cholesterol, but only on medications <sigh>.
As for treating lows, Karen...I'm sort of like Suz, but a lot depends on where I am and what I'm doing. If I'm out and about and not really close to meal time, I'd treat a 70 with maybe 5-10 g carbs. If, on the other hand, I'm really close to eating (half hour at home or already at the restaurant if eating out) I wouldn't bother to treat a 70. I'm extremely exercise sensitive, so if I'm out running around and I hit 70, I know I'll go even lower soon.
The other time I'd treat a 70 is if I'm going to be driving. I refuse to drive if I'm below 90-100, and even at that level I'd not drive if I've just been doing any kind of exercise. I passed out once while driving and do not EVER want to repeat that experience!
