#1 Take control of your regimen. Proceed as you’re ready, but lose almost all reliance on doctors and DE’s.
#2 Do thorough basal testing whether you are on a pump or MDI. You just cannot come up with accurate bolus rates if you don’t understand your basals.
#3 Come to forums such as TU daily and learn. After two years of daily vsits, I still learn new things daily.
#4 Carbs. I’m becoming more convinced every day that carbs are our biggest enemy. I don’t mean eat slow carbs either. You have to cut them back significantly. Being able to cover anything with insulin I believe is a fallacy in the long run. You might succeed more times than not, but you’ll be adding weight, higher BP, and all the other nasties.
