I used to work as 'breakfast b!tch' at a hotel... at to be there at 5am. OUCH. I am sooooo not a morning person (but I DO love coffee!!)
Go to bed earlier than usual. Start with 30 minutes, then an hour... it will help soooo much. Even if you can't sleep, keep the t.v. off, the lights low, and read. The point is to start shutting down your brain, not stimulating it.
Shower in the morning; it will help wake you up. Lay your clothes out the night before. On your way to work, crank the AC (cool air is proven to help wake you up) and turn on some tunes and SING... singing gets the blood and oxygen flowing!!
And this sounds silly, but do a few jumping jacks before you get into the office, like in the parking lot. Again, this wakes your body up and gets you going :)
