Need a Rest

I wake up and I'm tired. You know how when you wake up you have no power in your limbs? Yeah, that's how I feel when I get into work. What's with that?! And to top it off...my dog won't leave me alone...I'm afraid I'm sick or something. My eyelids are heavy, my head feels like it weighs a million pounds and my energy level is so low these days. Perhaps it's winter getting to me, perhaps it's my immune system giving in to all the germs that co-workers are graciously sharing with the office, or perhaps it's my spirit getting tired with the humdrum routine. Dunno which it is or if it's a combination of them all but I'm yearning for a break, a rest, something to re-energize me.
