When you feel like you're having a low blood sugar, but test fine (i.e. 120) (and if you have a CGM, it doesn't show a downward trend), what do you typically do?
Do you treat it as a low, even though you may not be low in terms of blood sugar? That's what I usually do to remove the low symptoms (i.e. have some candy, soda), but then it usually leads to me to end up higher than I'd like to be.
Does anyone just ignore the symptoms and see if they'll go away while hoperfully staying in the "normal" range?
I just ignore them. Sometimes I test several times, because I’m absolutely, positively, completely certain I’m low (or, sometimes, high). And it tells me I’m 96. It will say the same thing each time I test, so I just go with the meter and figure I feel funny. I trust my meter a great deal more than I trust my feelings. I know, at least for me, I frequently feel low the day after I’ve had caffeine (which I don’t usually have much of), so it’s just an after-effect of that. Anyway, basically, I say that feelings can be very misleading, so go with your meter. It’s not perfect, but it’s the best you have. (Your feelings can be changed by so much stuff - how much you slept, what you’ve eaten, whether your boss/parents/stranger on the street yelled at you, etc. But a meter isn’t affected by those things.)
Side note: you have a CGM, so this probably isn’t true for you, but your sugars can read high if you have sugar residue on your fingers. So you might want to wash your fingers off if you’ve just been eating sugar-covered gummy worms or just stuck your finger in a bottle of juice.
