I just noticed today that there is no noticeable issue there anymore. It's probably been that way for months. I don't have to strain to use ";" or ":" or think about the movement difference between "o" and "p". I don't have to think harder about "," or "." - in fact, I don't have to think at all.
I remember thinking I might not ever be able to type like I used to, and now here I am.
Crazy. Thank GOD the brain can reinvent itself. It's an amazing thing.
