Yes. I suddenly get onsets of, hard to explain, almost like a confusion. It's like my brain goes dim or something. I can't think of words. I can't even type clearly. I've been trying not to edit my posts when it hits so I can show what I mean. (This is hard, it is embarassing.)

I often confuse words. I will say "good morning" in the afternoon and "good afternoon" in the morning. This is a daily thing now, and lots of people call me on it. But, the sudden loss of words just comes suddenly. It can last a few minutes to a few days. It also effects my ability to read clearly.
