Quick question: Ergonomics?

Over the course of the last few weeks, I've noticed that I've been exhibiting symptoms of carpal tunnel syndrome. I know that my current desk set up is not the most ergonomic. I recently got a new desk, which is helping, as I have a lot more work space and can push my chair in closer to the desk.

 I'm also looking to add ergonomic accessories, bit by bit as we can afford it, as they tend to be pricy.

I currently use a rest for my mouse and keyboard, and also wear support gloves while on the computer.

Do any of my fellow writers suffer from carpal tunnel or other stress related injuries? If anyone has any tips for how they deal with it, I would be most appreciative.
