Like "What is your treatment method? Lantus? Pump? As to why you aren't feeling it, if you become too used to going low you notice it less. I would make sure you set up a system for someone to check on you in the mornings until you get it figured out. I went through a phase where I kept going low early in the morning and I stopped noticing until my sister (fortunately) noticed I was breathing funny and got me up enough to get me some juice. That happened at two different times in my life.. both times I was using Lantus insulin and had to adjust the dosage."
