Carl suggested that after working for several hours to get unstuck, he
was really thirsty. He suggested that everyone should carry at least 1 liter
of liquid water, and preferably 2 liters. Carl also noted that he had some
candy bars and hard candy for quick energy, but due to the dehydration, he
did not have any appetite for sweets. He did have a craving for salty foods,
probably to replace lost electrolytes. Now he carries some salty snacks as
well as sweets, and also carries powdered sport drink mix. However, he
advised to mix the sport drink not as strong as recommended on the package.
The idea is to get lots of liquid ingested along with the electrolytes.
