Hi Elizabeth,
It can also depend on how you treat (over-treat?) your low.
I use to treat lows with anything I could find: OJ, chocolate syrup (why bother to mix it in milk?!), candy bar, crackers, etc. In those low, panicked moments, I would eat everything under the sun. Which would then drive me sky high, often for the remainder of the day. For the last 2-odd years, I’ve been using glucose tabs to treat my lows and it’s worked tons better. Each tab is 4 g carbs, so it makes it much easier to get the right portion size when treating a low. No guessing. My net result is much fewer post-low highs.
Cheers, Mike
