So, when I first started the Dexcom in August, the buzzing alone would wake me up if I was low. Now, I'm not hearing it, nor am I hearing the beeping that goes off if you don't "snooze". I only wake up after I go below 55 and it starts beeping constantly. I'm not sure if it just isn't beeping after a certain time (it does during the day, still), or if I'm just turning it off in my sleep.
Any tips? The amount of lows I'm not catching till late is starting to worry me.
