Like breathing, sleep is a fundamental human requirement. It has even been said that one could survive for three times as long without food as one could without sleep. One of the better known experiments on this subject, found that depriving rats entirely of sleep resulted in their death, or near-dying state, within 11-32 days.
No people can not go without sleeping and still surviving for more then a couple months. Even after 2 days no sleep you would feel "dead tired". When you sleep you get enerygy and its is important for your growth.

Gudakesh means someone who has control over his sleep. Since Arjun could go for days and days without sleep hence he's called Gudakesh by Lord Krishna.
