I've had this happen but thankfully it went away. I think I've had two bouts of it. It's the worst. When this happens, I also tend to get words wrong... like saying "good morning" when it's 7pm... which I realize happens to everyone from time to time but it happens ALL the time and I start to sound nuts. And I have Freudian slips constantly. Make it difficult to communicate intellectually.

I'm very thankful that this seems to be a transient issue for me, at least for now. It comes and goes. I haven't had it happen in a while which makes me happy.
