[QUOTE="Cumbrianjudith, post: 2681605, member: 309126"] Can I slip in here with another Libre 2 query? Some lovely replies here that was information new to me ( even tho just been on 4 week diabetic course) as a new Libre 2 user on type 3c diabetes: I didn’t know it’s ISR and not BG they measure, nor the time delay or 15% +/- accuracy etc! I am now on my 4 th monitor and changed from humulin 1 to Toujeo and Fiasp insulins, and thought after 7 weeks fine tuning was almost getting the balance right with the vast majority of readings in the green 4-10 zone, taking 40 units as background and 6 ish with meals. I intermittent fast 5 days a week with swimming and no food for 16 hours. Then last night, 4th after adjusting Toujeo a bit upwards from 37 (when got no hypos but some hypers) I was woken by alarm reading 2s ( ate some nearby shortbread) , went back to sleep and off it went again within the hour ( more sugar rich snack), and again a bit later when had to get up properly and had bread with honey( huge spike). Then off to swim with BG in 10s, and for first time since wearing monitor doing exactly same swim of 45 mins BG was 2.9 getting out of pool ( 3 big glucose sweets designed for hypos). Has gone off again at 3.8 only 1 hour after eating cottage pie dinner…. I thought this all very odd and did a conventional BG finger tip blood test which recorded 6.8. The question is have I got a rogue monitor that is misbehaving, or has my body suddenly ‘changed’ in response to insulin? I am definitely not keen on stuffing myself with sweet foodstuffs. This am reduced the Toujeo down to 38. Any suggestions, I am on my own now to adjust meds.? [/QUOTE]
