I am not back at work, but going through the same thing. Writing used to come naturally and just flow but now it is so clunky and I can't remember when to use what punctuation and for some reason its and it's baffle me to no end even though I know the difference. Just like you, the fancy big words are not coming to me either like before. Maybe we just have to relearn and practice for awhile? That's what I keep wondering. I know what I type is a lot better than a year ago..
