Fiasp is a faster actin insulin from NovoNordisk. Have any of you tried it? If so, what are your experiences with it?

"Adults with type 1 and type 2 can now choose Fiasp, which can be taken up to 20 minutes after starting a meal and still be effective. Fiasp (“fast-acting inisulin now available in US pharmacies. A quicker version of the mealtime insulin NovoLog, Fiasp was approved by the FDA for adults with type 1 and type 2 diabetes last fall.  
Notably, Fiasp is the first mealtime insulin without a pre-meal dosing recommendation – Fiasp can be taken as much as 20 minutes after starting a meal, while other injected mealtime insulins are best taken 20 minutes before eating. This flexibility is due to the faster onset and offset of this insulin. (It is still strongly recommended that users take Fiasp before the start of the meal when possible, but the option to take it up to 20 minutes later does add extra flexibility when necessary.) Depending on the amount taken, Fiasp begins lowering glucose in 15-20 minutes

This thread includes some descriptions of people’s experiences on Fiasp: [FDA approves Fiasp - #54 by Beacher](https://forum.fudiabetes.org/t/fda-approves-fiasp/2206/54)

I thought Aaron’s post in particular was interesting:

> Hi @allison - I have been using Fiasp since April 2017 in my Omnipod. I am in Canada. My endo prescribed it off label for pump use. He said it was not approved for pump use yet becasue they had not completed some studies of using Fiasp in a pump. I think the issue was there is no guidance for doctors on the pump settings given - as in how the pump settings should change with Fiasp. Here is my experience summary that may appear elsewhere on the internet. Changing from Humalog to Fiasp in an Om…

I think you should try it because everyone should try it, but be warned it has quirks!
