There have been a few posts around the place as to what is the best music for coding, etc. While music can certainly make coding more enjoyable, I don't believe it actually makes me more productive and in fact probably distracts me more as I want to mess around with iTunes playlists, ratings and find good music to listen to.
I find that the best way to increase my code output is to get my brain active. Moderate exercise say at least a good run once per week keeps my brain "refreshed" and when i need to code hard core I find that Red Bull helps a LOT.
Coke is a second and Coffee is third in line with how effective I am when programming. Red Bull for me is like some magic crazy juice that unleashes my brain to do some super coding. I probably sound like a drug addict Artist who does his best work when on Cocaine or something, but it's oddly true. I have a friend who is the same, except his drug of choice is V.
The thing that isn't good about this is that I would imagine that drinking Red Bull all the time is not good for my health, since it's loaded with caffeine, sugar and food acid so I try to drink it only when I absolutely must, which is around the time when projects are due.
So what healthy alternatives do you use in order to increase your coding output and stimulate your brain activity?
