The next time you have to go to work after getting very little sleep, try this little trick I found in the June issue of Health magazine.  Get small caffeine hits throughout the day.  Instead of guzzling a 32 ounce mug of java, start with a 4 to 6 ounce cup of coffee. That’s about ½ a mug.  Then drink another 4 to 6 ounce cup in a few hours.  Studies show the low-dose method works better to keep you alert when you’re tired. Researchers found that shift workers and others who work odd hours get a better boost from small cups of coffee, but also they performed better on cognitive tests.

Another quick tip, this one to keep you awake during long meetings. Try sipping something cold.  Ice water or iced tea are good choices.
