For me, lots and lots of water all day helps. Keeps the blood pressure up a little. Also, keeping physically active through the early afternoon can help. Conversely, sometimes I find a 30-45 minute nape at lunch time helpful.

If you think the Snickers plus the caffeine is the only thing that is going to do the trick, it's slightly less unhealthy if you eat the Snickers in small bites over a couple of hours, and drink maybe a less caffeine and sugar in your guzzle.

On the other hand, a Snickers and a Big Gulp once a week isn't really much of a big deal health-wise. If it was every day, or twice a day, that would be different.
