New dosing technique appears to work
I read recently on the Dana Lewis and Scott Leibrand DIYPS (do it yourself pancreas system) about the beneficial effects of taking a small “early” pre-bolus about 60-90 minutes before eating. The idea is to have some insulin peaking just as your meal hits your gut. That way the liver can play its normal role of soaking up the initial surge of glucose coming from the small intestine. That’s the theory anyway.
The danger of doing this is that you don’t want to go hypo before you eat. So what I did is a variation of the super bolus technique whereby you “borrow” some of the immediate future basal rate, deliver that insulin immediately and then compensate by turning off the basal. So I borrowed 1.1 unit, delivered it at 11 a.m. and then used a -100% temp basal (turned off essentially) for one hour to make up for it.
I then did my usual pre-bolus and extended delivery for my late breakfast. I’ve done this breakfast many times and my usual BG line is a rise above 130 for an hour or two. I can knock it down with a post-breakfast brisk walk. As you can see my post meal line settled into a nice 90-100 trace.
Overall, a very good day for me:
96% Time in Range (65-140 mg/dl)
4% Time low (< 65 mg/dl)
16 Standard Deviation
90 mg/dl Average
