I will arrive from Lima to Cuzco and go to stay at Urambamba for one night. Next morning, go to Machu Pichu, spend a night there and then heading to spend my third and fourth night in Cuzco. Base on this, should I take diamox since Lima or start when?
I used to have terrible headache when I went to the mountain about 2500 M high. So, I'm a bit worry about this trip.
