Mt Whitney Zone Forums General Discussion recomendations for an acclimatization route up the summit?

Many years ago I did Whitney with a group of friends, none of whom had been to 14K before. Shortly above Lone Pine Lake, one of them pulled up and said he felt terrible, and just looking at him we could see he was hurting. He was ready to head down, but we convinced him to have some food and water, and rest for 30 minutes, and then make a decision, assuring him at least one of us would return with him if necessary. He took a couple of Diamox as well, and 30 minutes later he was much better and decided to continue. We all kept a close eye on him, but he seemed to get stronger as the morning wore on, and made the summit (and back) without further trouble.

Have always wondered about that incident, and the role that Diamox might have played. Your post confirms what I suspected, that it might have helped, at least to some degree.
