Sleep

Everybody needs sleep. In fact it is important that you sleep. No matter how important it is or how fun it is to stay up all night to chat with friends or do other tasks, you must sleep. Deprivation of such a thing as sleep could cause your mind to unhinges and cause various physical problems such a cold and other sickness.

If you are in fact sleep deprived then perhaps you been up too long. Catch a little sleep now and then and you should be able to rebalance yourself out once again. As the saying goes, "nothing is worth loosing a little sleep over" or "sleep on it and your thought should be sorted"
