> I've been meaning to experiment on myself a bit with some glucose tabs after a long day of code

Anecdotal feedback - they work great for short bursts of activity. I use them when playing multiplayer games at night. Given my opponents are usually young and fuelled on caffeinated sodas I need some kind of edge after getting home from work. When I stomp a lobby on team deathmatch it's usually after popping a couple of glucose tabs. A good low-GI meal does much the same, but of course isn’t as convenient.
