In Cusco. Altitude sickness is kicking me on the teeth. Very very very sick. I sweat through my bedding. Did not sleep. Got up to pee and could barely walk my head hurt so bad. I need to try to walk to the pharmacy.

And I need to be done today because we go on a three day trek tomorrow to Machu Picchu.

Not really sure how that's going to work.

Hmmm. I'm also waiting to throw up at any time. Life at 11,000 feet. I once jumped out of a plane at 12,000. No wonder.
