Sore Neck

Do you ever get neckaches from sitting in front of the computer for too long? I sure do!! When I'm working on the computer, I'm constantly having to take breaks to stretch my neck out, rub it, etc. For some reason it just gets so tense, even when I'm not stressed about anything. It started doing that when I was in college and in front of my computer all day. I think it's partly the way I sit. I should really try and watch my posture as much as possible. A sore neck makes working on the computer absolutely miserable.
