Very well written compelling experience. Unforgettable.
My ER doctor was negative toward the use of Diamox, as it can cause dehydration and you don't know it until it's too late.
Was that ER doctor the one who treated you in Lone Pine? If so, that says a lot. He seems to be very experienced at this being on the front line for Whitney hikers. Makes me wonder about trying Diamox or not. I've found benefit using a small canister of O2 (6oz 18L of compressed 90% oxygen). Probably not enough benefit if one is fighting HAPE, but it helps for us "sea-level sissys" with the usual mild AMS headache and short breath.
Diane, will you use Diamox again when you go back up?
