I've never been a drinker, but for years and years I was a folk dancer (to a limited extent, I still am, but the herniated disc curbs much of it).
There were weekends at festivals where I had almost no sleep: 5-mile parade in the mid-morning, 3 short performances in the afternoon, full show that night followed by dancing with the other groups until 3:00 AM, bus ride back to the dorm. It was awesome. :D
In contrast, over the last four days, I've had a TOTAL of roughly 8 hours sleep (altogether, not per night). That's just like the old days, true. But, if I add that I'm to the point now where I'm REALLY looking forward to my root canal on Monday, I think you'll get a better picture of my current sleepless nights.
