So he was 300 after soccer practice, in combination with the delayed pizza spike from lunch 6 hours earlier, I chose to correct with .5. Well not an hour and a half later, I do his bedtime check and he's 55. I doubled checked...58 crappy. He didn't even feel the drop of over 100,points. Well he gets his 3 glucose tabs. I wait fifteen and check again...55 WT! I dump strips and get new ones..84 whew! Much better. Don't know what it could have been.? Anyway, extra carbs for tonights snacks.
