Thanks, Harvey.

Googling the sub acute mountain sickness turns up information about people dying of congestive heart failure due to prolonged exposure to high altitudes. You would think that would be described more as the "acute" version.

"MCT" turns up "Medium-Chain Triglycerids," a category of oils manufactured from palm and cocoanut oils. They are said to help with treating food absorption disorders. I wonder if it would help people with AMS after they lose their appetite.

Mastiff: Many people hit the AMS threshold after Trail Camp. Eating more earlier would help. But acclimatization might help more.
