Okay, starting to make sense. The 1st couple of days were strange with some lows and corrections whilst I got used to the new regime.
I have one overnight basal of 15u instead of a split dose of 9u am/pm
Over night highs not as bad, typically peaking at 12 instead of 15-18
Morning BG still OK @ 4-6
Averages dropped from 10.1-8.8
Time in target up to 60% from 48%
Estimated A1c down from 64 to 61 (its been 64 for the last couple of yrs)
Carb insulin sensitivity 20/1
I was expecting to be using more bolus, but that's reduced too, typically 7-10u as opposed to 10-12u. Total daily insulin down to 22-25 as opposed to 30u.
Basal is supposed to be around 50% of total requirement. Mines closer to 70%, but I don't feel like tweaking it much more.
All in all very satisfactory. The libre is a revelation, looking forward to going onto a pump.
