thanks Mike, I am disappointed but I also learned so much that I didn't know going into this experience--so that my next attempt has a greater chance of success. The things I didn't know were things I missed in training--not doing any training with a heavy backpack on, for example. The nausea I've encountered before at all elevations, so for me it's a combo of needing to train myself to eat big breakfasts at an early time, and eating slowly to not upset an already delicate stomach at altitude.
