Actually I wonder... Even if we could give up sleep, would we be able to resist it? An example is our diets. For the longest time, certain nutrients are needed, so our body makes us crave them. Now we have these things in no short supply and it's hard to resist them (some failing) because our body still tells us to have more even though we don't need more. Sleep is similar. Even sometimes when having gotten plenty of sleep, your body will tell you to sleep when you don't really need it because it's programmed to at some times. Even without the need, that "craving" for sleep wouldn't just go away just like the craving for sugar and salt don't go away just because you've already had enough to meet your needs.
