I forgot to mention hydration. I was very well hydrated--at least 8 ounces every waking hour on the hour beginning 3 days before both summits. I also did the aspirine regimen that others on the Portal Store board have recomended--the first time. I didn't do it the second time.
Regarding eating less, that is an interesting idea. Some have said that at altitude, the body doesn't put much effort or energy into digestion. I think that might be right. I certainly didn't stuff myself either time (and ate far less than the 1500 calories a day than I packed), but (turn an eye if you get grossed out easily), the peanut butter in a peanut butter and banana sandwhich that I ate 3 hours earlier didn't appear very digested.
In the final analysis, however, I don't think that eating less would be much help. It might reduce vomiting, but undigested food didn't cause double vision and sluggish thoughts.
Not that it matters much for AMS, but my physical fitness level is very good. My muscles and lungs felt great and I had almost no residual muscle soreness after the last summit attempt.
