Thanks for saying this. I already use Vim (in my browser too). I've used it on and off in an editor as well. I've tried reading books (like I mentioned in the post) which is something you only do when you're truly desperate. For some of us, our body will only allow so much.

I am sure the OP was just trying to help. I, too, when I started having such problems chalked it up to "surely some adjustments will help". And they did! But it never quite ceased.
