Want to switch to fiasp after 15 years on novorapid

I swapped from NovoSluggish to Fiasp over a year ago.
It certainly works better for me but it is not perfect.
- it’s shelf life out of the fridge is less. This is mostly a problem when travelling so no trouble during pandemic.
- the speed of Fiasp has slowed from the euphoric speed when I first switched. It is still better than NovoSluggish which I used to have to bolus. 40 minutes before eating. Actually, the biggest gain for me is when I suspend my pump for exercise. With NovoSluugish, I had to suspend more than an hour before exercise which meant there was plenty of time for the exercise to be cancelled. When I started Fiasp, I could suspend when I jumped on the bike, now I need to do it 30 minutes before.
- I find Fiasp is slow to respond to highs (over 10). On the few ocassions when I spike that high, a bolus seems to take forever to start working and then when I decide I need another correction, my blood sugars fall fast. I am still in the trial next error stage with this but mostly because I try to avoid going that high so don’t have much to trial,with.

Overall, Fiasp is not the fiasco in your thread title but it is not perfect either.
For me, I don’t feel it would be fast enough for looping.

So is there anything faster?

I can’t comment on experience as although I’m being switched over to Fiasp, I don’t actually have it yet. There are YouTube videos and blog posts about Fiasp

Fiasp is essentially a faster NovoRapid, as the insulin aspart stays similar but it contains an amino acid and Vitamin B12, both of which speed the Fiasp up, giving it its name.

Antje also linked my thread which is also helpful, people have given experiences of Fiasp over there after I asked for benefits and people’s experiences.

At the moment, the only insulin that I think would work for me is human insulin that comes from a healthy pancreas.
As we all knows, a cure is only 10 years away

I had a go with Fiasp in my pump a few years ago and liked it initially but found it less effective after a few months which some others have found too so reverted back to Novorapid. I also had delayed highs after eating fatty foods as I guess the Fiasp was in and out of my system by the time it was still processing the fats. I still use Fiasp in pen fills as it’s good to bring down occasionally high peaks that I know a pump correction would take too long.
