This morning I was awaken early to find a surprisingly high (300s!) blood sugar... I tested ketones and they were also present in large amounts. (The long story is here).
When I started on the pump, the CDE who trained me told me to take six units of insulin by syringe, then to monitor my BG going forward and correct as necessary, just keeping in mind that those 6 units wouldn't show up as "on-board" by the pump. It seemed arbitrary and not based on any actual measurements, but it's easy to remember.
Since moving and switching doctors, I've been given different advice: to calculate the correction based on my BG at the time, then to do some other mathematical calculation (I forget what it is) to determine how much insulin to take. It made sense, but was far too confusing to remember, and too hard to calculate in my head, especially in the middle of the night with my head spinning.
Obviously, since I can't remember the second bit of advice, I took the first. But what is the RIGHT thing to do? Is there a right thing, since there's no way to really know how long the basal was knocked out for? Is the right thing (keeping a scientific calculator at my bedside) really practical?
