I'm sure someone on here is going to say clear off and stop asking fool questions: but I have another. i don't understand spikes. If you eat food you get a spike as the sugar hits your bloodstream. So is the idea to keep the spike as small as possible? you can't eliminate it can you ? It seems odd to me to test for BG 2 hours after a meal. It is too late then. The time to test is after every mouthful. So you can stop eating. I'm missing something. Please advise.
