You may feel dizzy and weak and find yourself breathing heavily—signs that the thin mountain air isn't giving you your accustomed dose of oxygen. Take it easy, and rest often for a few days until you're acclimatized. Throughout your stay, drink plenty of water and watch your alcohol consumption. If you experience severe headaches and nausea, see a doctor. It's easy—especially in a state where highways climb to 11,000 feet and higher—to go too high too fast. The remedy for altitude-related discomfort is to descend into heavier air.
