I have matched my insulin to carbs for a long time now, self taught no DAFNE course for me!!
I use the old fashioned portion system, this is what I was given when I was diagnosed in 1975, and Ihave worked out that I need 2 units of bolus for every portion (10g) of carbs except when I first wake up at 6am when I have to take 20 units of bolus to stop me going sky high I then take 8 units at 8am to cove my breakfast of 4 portions. It is this extra 20 units that I am hoping the pump will do away with. I will let you know how I get on
