Wow, you remembered the headache thing. Well, eventually my doctor recommended a brain MRI to rule out a tumor or aneurysm. The results came out flawless, which led him to believe that they were just tension related. I had been doing a lot of irregular exercise during that time. Just pretty much being sedentary during the week with huge blasts of intensity during the weekend. Since then, I've tried to even-out my physical activity and I haven't had the headaches since.
This past September, I spent a week above 15,500 in Bolivia and climbed as high as nearly 18,000 without a problem. Thanks for asking.
My girfriend and I are going to check out Sill (heading up this evening from LA). If we don't get far, we'll just chalk it up to training.
I'm kind of excited to go up against the cold, test out our 'gumption', skills, and equipment.
If we do make it anywhere, I'll be sure to post.
