[Diabetes-Talk] Dexcom G6 off from finger stick

Sun Mar 1 21:25:30 UTC 2020

Hello,
I also take 1 unit of Humalog for every 3 carbs. I am more sensitive to the lows than the highs. I am sensitive enough to lows that they will wake me up in the night. If my sugar gets close to the 300 range I sometimes can get a little queasy.
