There's probably not a good rule of thumb here, but how far should a person descend if they start to feel the effects of altitude sickness? Does it make sense to go back down, say, 1000 feet and wait for an hour to see if the effects diminish, or is there some other standard? If I'm out for a three or four day trip and started to feel like I was getting altitude sickness, I wouldn't want to lose too much mileage by going down farther than necessary? I just want to see what others have experienced on this.

I can't remember ever having to deal with altitude sickness for myself (or else I didn't realize the symptoms at the time), so I don't have much experience in this area.
