According to my pump, for the last 31 days, I have used 34.59 units of insulin per day (basal and bolus) and eaten 157 carbs per day on average.
When I was first put on the pump, I remember they set my reservoir to hold enough insulin for a 300 carb/day average (they were using the FDA guidelines for someone eating 2,000 calories per day). That was really awful because I ended up wasting lots of insulin that first time. I don't think my nurse took into account the fact that I am a small-boned, 5'2" female, not the 5'9" male for whom the FDA guidelines apply. There is no way my body could handle 300 carbohydrates every day (on the other hand, there is no way it could handle Atkins levels, either - I feel great taking in 150-ish carbs each day).
So what are your averages? Do you feel they work well for you?
