You just lay curled up in the fetal position baking in the heat. When the coolness of nightfall comes you get up and start walking for home. Along the way you find a mutant cactus. It has these creamy white flowers. You have eaten these before. You pull off a flower and a powdery scent fills the air. You bite off a petal. It is juicy wet and a bitter melon like flavor fills your mouth. Nasty with a pleasant after taste. It helps give you energy for the walk ahead. and it re-hydrates you as well.
