There might not be an answer to this dilemma, but I’m hopeful. My son is about to leave for his freshman year at college. He sleeps so deeply that the CGM alarm does not wake him up. (He also tends to fall back to sleep when his clock alarm goes off, but separate issue.) The vibration while he wears it isn’t working either. A diabetes coordinator suggested we put the CGM into a glass filled with marbles to enhance the sound when it vibrates. It was loud, but it didn’t wake him up. Since his diagnosis, we’ve checked him at 2:00 am. Now that he’ll have one or two roommates, I’m sure they’d appreciate an alarm going off only when necessary. Plus, my son would get better sleep too, and he’ll need it when the stresses of college life really hit him.
Thanks for your suggestions or successful fixes.
