Lol...right Steve. I've always been a low water drinker. It's not a conscious effort or anything, I just could not have drunk 5 liters if I wanted! I've read many threads here on how much water and went with what my experience has been for me.
I would have filled up one liter at the switchbacks, but my head was really pounding by then and I wanted to get down lower as fast as I could. Now in hindsight (and the ability to think straight) I should have gotten the water since it would have probably helped with the headache a bit.
I guess that's part of the learning process!
