I've had cf related diabetes for 24 years now and i have always taken long acting insulin. The key to eating and maintaining good blood sugars is knowing when the insulin peaks ( works hardest). I have things pretty much down to a routine, to where i know when i can have sweets and how much to have. I check my blood sugars alot ( 6-7 times a day) and that helps me to keep track of how things are going . Of coarse when i get sick the whole routine changes, and i have to adjust to that for a while, but it always goes back to "normal" eventully. I takes time to notice how different foods affect your blood sugar and what amounts work for you, but once you get the hang of it, it isnt too bad.~Diane 39 cf / diabetes / b.cepacia
