I'll bet it's especially difficult using Dvorak after a break.
Well, it is and it isn't. I hadn't really got the hang of Dvorak anyway but now I've completely lost all my ability with QWERTY so I'm stuck with it. I can type fairly accurately if I keep my eyes closed but that's not really practical so I'm using the backspace key a lot.
I think I'll get the hang of it eventually but I did think I'd be able to go back at any time. Now I know it's not that simple. I wonder if this was a really bad idea.
