I've tried everything. I have been waiting 20 minutes after bolusing to eat, and making sure I'm not eating all fast-digesting carbs. My endocrinologist looked at my dexcom last week and recommended that I wait 15 or 20 minutes to eat, (I am) and try not to eat something that is 50%+ of sugar too often. (Check.) But even so, I am spiking way past where I should.
For example, I ate 40 carbs for breakfast- a homemade waffle (not a lot of sugar) and berries. I waited 20 minutes to eat, and right now (an hour later) my dexcom graph is showing 241 with a straight arrow up.
What gives, diabetes?
