Nick Smith says he and his partner have experienced hallucinations while hiking in the mountains. He's wondering if Dr. Tan, you know, if anyone has experienced similar events. When we think about how many calories we need, it's on the scale of over 6,000 kilocalories a day. So with altitude sickness, feeling nauseated, not having a good appetite, it's very hard to get over that number. And so high altitude, cerebral edema can cause some mental changes as well.
