A recent experience leads me to ask...

1. Have you ever "hit the wall" / "bonked" when hiking? What did you do? (I didn't but I was close)

2. Just as runners use gels and sports drinks, do you think such things would help backpackers regulate their blood sugar and muscle glucose to increase performance?

3. Did you ever overdo it and lose your appetite when hiking?

4. Anybody out there drink more than six liters a day on a "big" day? How much do you drink?
