I probably won't be much help considering I spend all my free time playing video games or watching movies. That's pretty much all I do
I usually workout an hour a day. When I joined my gym back in 2002, they told me, "After you start exercising regularly and lifting, you'll find that you have more energy than you know what to do with AND you'll get better sleep!" Err.. I'm still kinda waiting for that :P (and I eat *VERY* clean), so I'm in the same boat as you.
I just started a 6 week course in Calc I at my college, so that eats up about 3-4 hours per night of my time.
