I had mild pain in my wrists in the late 90's I switched to ergonomic keyboard, got a good office chair, and switched to Dvorak layout. I did this for my work and home environment. One additional step I had to take. I removed they armrests from each chair and have continued to do so with all chairs. I found myself leaning into the armrests too much to the extent of causing abrasions on my elbows. With removal of the armrests I work and play at the computer with better posture. I mention this only because what works will vary between people and I think it's an important change. Also, I have no idea what to credit with the pain of my wrists going away. I suspect Dvorak, but it was probably a combination of factors.
