My husband and I are new at this (50 days post , C6/7 incomplete) , and AD is one of the more scary things that I've been reading about. Especially since we are in BFE, and an ambulance takes , I shit you not, 1 HOUR to arrive at our house. We have had to call 911 twice here for other reasons, and its not pretty. The volunteer guys who show up first aren't even EMT's or authorized to carry Nitro. So anyway, Scary. How often does this really happen? I understand that I need to be aware of it and educated, but should I be patiently expecting it or is it not very common? Also, am I going to have a problem getting the doc to prescribe nitro so that i can have it on hand?
