Thank you Steve, I appreciate the information.
For those who have experienced AMS, how accurate/often do you use the Lake Louise scoring system (headache, nausea, dizziness, fatigue, ability to sleep) to decide whether to push on or turn back, ie if you fall into the mild AMS scoring category (3-5).
I guess that's up to the individual's tolerance of risk vs the adage that headache plus nausea/dizzy/fatigue means it's time to turn back.
