RA, I thought about you a lot during my ordeal. Your description of the shivering. My whole body was sore and moving was really tough. I'd go between shivering and sweat quickly, and have no easy way of adjusting my clothing/temp, and no one could come in and help me.
It sounds like you suffered quite a bit, maybe more than I did.
Somehow, deep down, the fact that my blood 02 stayed high the whole time, helped me feel I would make it.
I found the whole thing to be very emotional too. Even the slightest criticism of how we (Zelda and I) handled it made me say "fuck you" under my breath.
I took a bike ride yesterday and I actually found the lack of the 20 lbs pretty amazing, climbing I felt no pressure on my knees. Every bit of push seemed to translate into forward movement, vs any pain.
