Taco Bell Doritos Locos tacos. Cool ranch taco shell. 39 carbs. The particular blend of carbs, protein and fat in that meal just fits the insulin action almost perfectly in my DS. Now with the Dex I can say with certainty that I see no spike. I see no drop. I see a straight line for 2 hours now. Its almost like he didn't eat anything. So do you have a meal that 'just works" without a lot of work/guessing/adjustments/hassle?
