I have 3 echos but only novorapid cartridges for those echos. i dont have abasaglar cartridges that go in the echos, only the disposable pens in whole units, hence my inability to fine tune my basal insulin, and hence my being awake at 2am waiting for blood sugars to raise after therapeutic snack (not gone below 4 but want to see them up a bit before going back to sleep).
Got it, thanks. Yes, I remember those early days of uncertainty.
I'm busy all today, but I need to go back and read the whole thread to properly understand the full picture.
It sounds as though you are trying to regulate using your basal (which some people do) whereas I keep my basal pretty fixed, optimised for ensured stability through the night [in practice nothing is static for very long!!] and use my bolus for food and any corrections as the day unfolds. I have Tresiba as my basal, which lasts for up to 40 hrs, so daily changes take up to 3 days to come into effect; therefore its altered infrequently. Bosul changes generally provide a response in the 4-5 hr window. So if I'm too low I respond with more carbs; if I'm too high I usually just wait until the next meal bolus and then add a correction to the food dose. This avoids stacking insulin. If I'm uncomfortable about being high, I will get active, in some way, to reduce my natural insulin resistance and let whatever insulin is on board "go further". I rarely take a bolus correction within 4-5 hrs.
This means as I go to sleep, I always take a last scan. If I'm low I'll take a reassurance snack, but I trust my ratio sufficiently to feel happy that the snack will work. I only wait to confirm this if I'm taking a hypo, or near hypo, response. Then I want the confirmation that recovery is happening. If I'm above 8 I'll take a very small correction, just enough to nudge me back to 6 and then sleep through until either I need the bathroom or when I wake to get up. Unbroken sleep is
very important to one's overall metabolism. Broken sleep causes stress, which is fundamentally the enemy of DM and usually leads to elevated BG.
If your basal dose is in the low 20s, half units are pretty irrelevant. I take 10 basal units and contemplating going down to 9.5, because 9 seemed to be too little when tried over a 7 day period.
