B2Y, I do know exactly what you mean about that feeling of looking up at a steep hiking trail...and just being to fatigued to even think about it. But it just dawned on me that part of MY problem is the lack of sunshine the past few weeks. We've had maybe an hour or two here and there, but it is so dreary and it's starting to affect me. Come to think of it, what little sunshine we did have, I was taking a nap during that time!
I'm going to pull out the broad-spectrum lamp tomorrow and see if that helps any. May increase my vitamin D as well.
