Had a member of my group get severe AMS symptoms yesterday. I had two small cans, 50 use?, brand new. They helped her a lot. One can ran out quickly, after maybe 10 uses, so I was glad to have the second.
However, there is NO substitute for training and acclimitization!!
Interesting story, DavidK. Can you elaborate on the situation a little more. How bad was "severe AMS? HACE? HAPE? Specifically what improvement did she notice? How did she get off the mountain? Thanks.
