Might want to try another peak in the interim, maybe with a Diamox assist. Maybe Mt. Dana, a nice 13K peak you could do in a day from your Bishop place? Might help to build your confidence after your experience on White Mountain.
If you had an independent stomach issue, perhaps that dehydrated you and heightened your susceptibility for AMS....
I'm also a fan of Nuun tables. Electrolytes replenishment can be critical at altitude (where people tend to pee a lot), and particularly so if you are on Diamox.
