This is a great report. Thanks.
It points up some of the multiple factors that make analysis so difficult. Are the symptoms just plain AMS, or are they complicated by dehydration, or GI issues, or fatigue, or etc? Diamox is used as both a (partial) preventative as well as a (partial) therapeutic for AMS. The exact dose and timing is not so clear, not the same from individual to individual, not even within the same individual from trip to trip. This makes the science often turn into guesswork and lots of personal opinions.
One interesting point was that you recognized the need to move around as opposed to lying still at the rest stop. "Keeping the juices stirred" a modest amount is talked about, although there is not much scientific data on this. One breathes more (relative hyperventilation) while walking around a bit as opposed to the slower breathing (relative hypoventilation) while lying down and resting. The key is how much - just a bit, enough to help, but not too much which would further worsen the issue. Furthermore, if there is any fluid in the lung from very early HAPE, it is better to be upright.
Glad you seem to have a handle on what helps you. Hope you have success on the next adventure.
