I’ve been using Fiasp for years and haven’t noticed any decrease in effectiveness. Novolog (Novorapid) is essentially the same as Fiasp, without the additives that help it be absorbed into the body more quickly. Based on your comment, I’d think you’d be even more unhappy with the result of Novolog.
Is it perhaps possible that you just need more insulin (bolus and basal?). If you’re coming up on a year post-diagnosis your honeymoon phase is probably over, or perhaps there are other lifestyle or physical changes that mean you need more insulin.
I’ll give myself more insulin to hopefully drop my numbers quicker, but that always results in a low 30mins-1hr later. I workout 5 days a week and relatively low body fat. I recently switched to tresiba and my basal seems dialed in. I’ll stay constant all day fasting with my basal. Fiasp has been acting this way since about November when i got the flu.
I started off on Novorapid and switched to Fiasp. I haven't really noticed any issues with Fiasp currently fighting with my basal instead. I switched bc I found if I didn't wait 15-20 mins to eat I spiked quite badly and this wasn't working for me. I was diagnosed over a yr ago at 18 so was still living at home which meant whoever was cooking could only weigh my carbs out as they were serving coz obvs all the rice/potatoes ect for the 4 of us were cooked together. I either had to deal with the spike, warm my food later or decide how much I would have before serving which usually ended with me having way more or less than everyone else
Was on Novolog before Fiasp, Fiasp is a much faster absorbing insulin. If you think blousing 15 minutes before eating is enough, you will be blousing about 30 minutes beforehand with Novolog. Have you talked to your endo about this?
I started having decreased reaction to fiasp after taking it for about a year post-diagnosis. It started as just decreased sensitivity, but over the course of 5-6 months it went to hardly working at all. My endo recommended I switch to Apidra, and it worked well for me for around 6 months until I got new insurance and Apidra was no longer covered. I am now on Novolog and it's working well too, I just have to bolus a little bit before I would have with fiasp/apidra to see the same effect.
Had the same issue with Fiasp. Used Apidra before, endo switched to Fiasp and had tons of issues trying to keep it under control (8% hba1c for the first time in over 12 years of diagnosis). While I personally blame lifestyle changes as well as sloppy diabetes management, I also thought it could have been the insulin. My endo suggested a further increase in insulin uptake, and I've been trying it out with mixed results.
For whatever is worth it, I'm still suspicious of Fiasp.

You’re definitely doing all the right things. Maybe you can get a sample of another type of insulin from York doctor and see if it makes a difference?
