I returned last night from a trip to Thousand Island Lake, and was really surprised at my AMS symptoms.
We stayed 36 hours in Mammoth, 8000' with no symptoms. Then traveled into T.I.L. at 9800'. I had symptoms for another 24 hours! They weren't that bad, but I felt wasted -- tired, with occasional slight nausea. I was able to eat, though.
Finally, Saturday morning, over 72 hours after being at or above 8000', I felt good. I was able to climb Banner Peak, ~13000' symptom-free.
I have used Diamox in the past, because I usually get the symptoms. But this trip, with the initial stay at 8k, and the fact we were only going to ~10k, I thought I'd skip it.
Next time, I'll know better!
