Programming and stress

i'm in the middle of making a fairly sophisticated game. Most of the time I've spent on it so far has been just on the planning, how to get the physics and collision detection to work etc. I can only spent so long a day trying to work this out before i start getting stressed and stuff. i start feeling easily agitated and restless and it gets hard to concentrate on the game again. you guys have any tips for tackling programming stress? much obliged 8]

Take a walk (at least 2 hours or it does not count as a walk.)
Get drunk, write code around 4-5 am while having a hangover and listening to beethoven.

It always works for me
