How do you have your Sensor Settings? We have ours to repeat a high at 3 hours and a low at 30 minutes. But during the night, the pump alerted 3 times in a row. I gave her carbs with the 1st two( 70 & 74), but by the third, I felt I would be overfeeding what was then a borderline number (80) with carbs still kicking in. I am also fully now awake. We typically have the CGM alarm for lows at 80. Last night I shifted it to 70 as the SG was running about 10 points under the BG, and I didn't want to be awakened for non-lows if I could help it.
