Someone mentioned take a nap, and I completely agree. Here's what you do: pack your lunch every day (its cheaper, and you'll most likely eat healthier, both making you more alert). Go to your car at noon (or whenever you take your lunch break), put the seat down and take a 30-45 minute nap. Keep the AC or heat on, and if you're like me, turn the radio on and keep it on very low volume. Set your phone to wake you up. Go back to work, eat your lunch in front of your work station (while working, responding to emails, tickets, etc.) and you'll be very refreshed. Eat some foods high in natural fat (uncooked/unroasted raw almonds are great) later in the afternoon, but do not eat a lot of sugar or carbs. This has been working for a while for me so when I get home I can still work away on personal projects.
