It's 4am I must be lonely

Either I'm getting old or putting on more weight, I sleep shorter hours and wake up earlier than usual. I'm in my mid-30s and will soon sing life begins at 40 but I couldn't help but think have I been there and done that? Not exactly how I want to be asked, but suddenly, when it's 4am and everyone else's snoring, you're quick to think that you're all alone, waiting to be wasted.
