That being said, I don't usually eat while I use it, so I think raseol might be right, it's just dirty. Try rotating the stick around a lot, cleaning what you can get to, and maybe even compressed air.
I have that controller, too, been using it since FFXI as well, but the past week or so, whenever I grab it down from the computer desk, I hear that USB-off sound, then a few seconds later, I hear the USB-on sound again. A lot of the time, if I set the controller up on the desk while the game is on, then take it down again to play, it doesn't work for a few seconds, and then if I'm pressing a direction on the analog stick while it reactivates, the game will be stuck pressed in that direction until I do that thing with the controller again. Anyway, I'm thinking something might be broken in the wire, sucks because it's really a good controller, lasted quite a while.
