Caffeine tablets are my trick. Equal to a cup of coffee, without the sugar and calories. They last 4-5 hours and don't make me manic. You can take one or two as needed, altho there is a limit to how many you can take in a day.
I usually only need one at a time to get me thru the rough spot of mornings.

Other than that, everyone else has listed the a lot of good tricks.
