Hi all! I was previously on novorapid for 10 years then I was changed to fiasp as I was very insulin resistant in the morning. I was needing to take my novorapid 45-60mins before breakfast so we thought fiasp might be an alternative. My bgs have been like a rollercoaster since the change and tbh I still have to take it 30mins before breakfast. I actually feel im more insulin resistant with fiasp. I've gained weight since starting it am not sure if that's related. Well I stupidly ran out of fiasp at the weekend but had a spare novorapid pen and have been using it. My bgs are much more stable and in some ways I feel better. Is this common or just in my mind? Am thinking of asking my dns to change me back at my next app.
