Hello All, I am a passionate hiker and often venture into altitudes above 10,000 ft. I suffer from altitude sickness and get terrible nausea and migraines when I'm above 10,000 ft. elevation. I spoke with a friend in Colorado and he said that many of his hiking buddies use a product called Big Ox O2 in order to combat altitude sickness. They seem to swear by it. Does anyone on this forum have experience using this product?
