Finally got around to posting this:

First off, I'd like to say thanks to anyone who contributes to this site. Because of this site, my trip (aside from not summiting) was a relative success!

Myself and two friends reached Whitney Portal at ~5pm on Sunday, June 10, 2012 to begin our journey to the top. As soon as we arrived at camp I knew something wasn't right with me. By 8 oclock I had a terrible fever. I ate a quick dinner, and wrapped myself with every piece of clothing I brought with me (literally!) then went to sleep. By 11 oclock pm I felt the fever "break" but I was still slightly sick.

The next morning I was up at 7:30a with better health and good spirits. Still slightly feeling the effects of the fever, however I was in the process of getting over it. My group and I packed up our packs and headed for the Portal Store for breakfast. After breakfast, we headed up to Lone Pine Lake. During the hike I felt great, no signs of sickness at all. We made it there, but headed right back to camp. Afterward we did much of nothing the rest of the evening.

We started up the trail at 3:32a, and I was feeling good. We reached Lone Pine Lake right as the sun was rising. We hung out and had breakfast while watching the sunrise. It was incredibly beautiful. I did feel a very slight headache, which I assumed was due to dehydration. The next time I filled my hydration pack, I tossed in a couple Propel powder packets for some electrolytes. This seemed to help, and I continued on. By the time we reached trail camp the headache had increased. I was urinating much more than what seemed normal (about 7 times by trail camp). I decided to press on, but take it slow. One member of our party stayed behind for other issues. Upon reaching trail crest, the headache was unbearable. I sat down while gawking at Sequioa Natl Park to rest. The headache never went away, and I knew I had to turn back. Made it back down at ~3p still with a slight headache.

I'm assuming I had the beginnings of AMS, however the headache was my only symptom. No shortness of breath, no loss of appetite, no nausea. Could dehydration have played a factor? I did drink nearly a gallon on the way up. Of course I want to try next year, is there anything I could do better/change?

Here is my favorite picture from the trip:
