Yep, a whole lot Everything is so much more relaxing and open at night (well, if you're in a safe place, obviously), it feels so magical and the perfect scenery to traverse the friendly pony forums (and the rest of the internet) with It's scarier... but sometimes, scary can be good...
I've gone from a sleep schedule of 10PM-6AM to... um, no sleep schedule... Well, I stay up throughout the nights now that I can; the peace they offer is all worth it, to me Plus, it's cooler, meaning I've got more excuse to hang around under the bedcovers, and it works well for me with my aversion to heat too =)
