At 4am you are as alone as the last Tasmanian Tiger. You are a bundle of screaming nerves with no skin to protect them. Absolutely nothing matters: not women, not friends not ***, not money, not poverty, not friends, not lovers, not the future, not the past, nothing at all. All that exists is the terrible freedom of the insignificant blob of protoplasm that you are. You know in your soul that there is a strong possibility that nothing means anything. So you go back to bed and anticipate remembering nothing of this in the morning. The bliss of unknowing is your only hope in a world of hurt. Try it. Perhaps it will work. It never stays 4am forever.
