Currently 7.4 have changed my background insulin from Levimir to Tresiba and been battling overnight lows for the past 3 months, finally got it to a point where I'm steady through the night, the hospital advised me to take 22U per 24 hours about 4 months back and I've adjusted it down gradually to 13U per 24 hours which seems to be the magic number for me. Having settled there as a corrective dose 1U of novorapid seems to drop me by 2mmol, just trying to figure out the novorapid dose for 10g of carbs, once I've nailed that im hoping my hba1c will get better
