During the night & shortly before bed I often have CGM & BG numbers that do not match. Here are the 2 most common scenarios:
- ~1 hour after my shower, but before eating my bedtime snack: BG significantly higher than CGM, but usually return to similar before morning
- Under covers at night: Being under the covers in bed, regardless of sleeping position, cause slightly lower CGM numbers (not necessarily alert or out of range low, but still lower than it really is). After getting up for 10 or 15 minutes, it will usually come back to correct, but then back down if I get back in bed. If I lay in bed without the covers, this problem does not usually occur
Has anybody else had either of these problems? I use the Guardian 3 (with the recently updated transmitter).
