10 hours of sleep a night? Heck, that happens year round...

I think shifting my morning wake-up time to coincide with "sunrise" here would quite probably make things more depressing. At least, if it's already overcast and grey when I wake up, I can comfort myself with "but I slept late, maybe the sun shone earlier." But if I wake up when it's still dark, then I'm guaranteed to know when the sun never comes out all day long...
