Eek -- I'm sitting here shaking. After lunch, my dexcom said 152 and my meter said 133. I ate a spoonful of peanut butter and did a 30 min (moderate) workout. Right after, my dexcom suddenly dropped from 82 to 55 and buzzed. I figured it was an error, but grabbed juice just in case, then tested ... 32!? So weird, I've rarely dropped this fast.
Sorry -- I basically just needed to complain! (But, maybe people have a better suggestion for a pre workout snack if I'm not on the low side before starting?)
