We arrived in Cusco with some major symptoms of altitude sickness. Both of us felt extremely tired, had headaches, and even a little bit of nausea. We couldn’t drink enough water or coca tea, and forced ourselves to stay awake all day checking out this charming colonial Peruvian city. The scenery is spectacular and we are excited about the trek tomorrow. Mom has a few reservations about the difficulty levels, but I am encouraging her to stick with it as I think the reward of reaching Machu Picchu at sunrise Monday morning will be worth all the effort. Wish us luck! Love you all!
