ABC is at about 21,000 feet. We stayed here for 2 weeks acclimatizing. One day we ascended toward the North Col (23,000 feet), stopping short. Another day we climbed all the way to the North Col and descended. Then we climbed to the North Col and spent the night. I experienced a lack of appetite at ABC and ended up losing weight. This is common and is why we and several other climbers descend back to the lower altitude at Base Camp to try to regain strength. Some people have trouble sleeping in altitude. Thankfully, that's not a problem for me.
