Symlin and Fiasp

Wondering if anyone has experience with Symlin/pramlintide or the new fast acting insulin Fiasp. My t1 father was very recently prescribed these from his great new Endo that this sub recommended! Neith one of us had previously heard of either of them. Anything you have to offer about either of them is much appreciated!

Thanks for being such a great and supportive sub, my father and I are grateful to have you.
