Congratulations on your A1c!
I have a couple of questions for you since you are quite successful. Are you very strict on the diet? Meaning, are you only consuming 3 oz of protein at meals and sticking to the strick carb guidelines when you eat your veggies?
I am currently using Humalog for boluses to cover protein and fat. Other people on the DR. Bernstein site say not to use Humalog for boluses but to use Regular or Humulin R for coverage because it works better for protein and fat coverage.
I haven't made the switch just yet. I am still working on my protein size. I have been eating upto 5 oz at one time and my sugars show it. It's awful. Instead of eating real carbs or real sugar, to much protein can shoot a person over 250 anyway.
Keep up the GREAT WORK!!
