That's interesting - I didn't know that. I've had to reduce my Novorapid down to around half or just under half of what I used to take pre meals/snack and this seems to working ok so far for me, though not always - and post breakfast is proving really tricky as I keep hypoing straight after breakfast and then rebounding to quite a high level a couple of hours after. I managed to speak to my nurse a couple of days ago who suggested a couple of things to me. We decided that maybe if we can fix the breakfast/morning problem then the rest of the day might go a little smoother. One thing she suggested to me was that I reduce my breakfast bolus down even further. Another was to go back to injecting 15mins before my meal and see if that made a difference (I'd stopped doing this and just injected straight before eating as I was sometimes hypoing before I'd had a chance to eat my breakfast.) The other thing was to have another small snack about an hour after breakfast before leaving the house as sometimes I'm dropping before I'm even out the door in the morning. She also mentioned if I was still having issues we could discuss maybe trying a different insulin rather than Novorapid, though I'm a bit reluctant to do that just as I've been on Novorapid for years...hopefully one of these things will work! I'll give them a go next week. It's just so strange how it happens so suddenly - I really hope you get sorted with yours too and your nurse is able to help you get your BGs back on track.
