With meds, without meds, add ADD. Happens more often than I'd like. It seems to happen more in speaking than writing for me. Sentences trail off, forget I was talking…sentences stop -- train's derailed and I have no idea where I was. I will "know" a word, I can feel it, how many syllables it has or what it starts with, words that are tangentially related, but not be able to bring it out. Sometimes it's a case of there being no words able to express.

When it's in writing, I'll find that I've just been staring at the screen, at a total loss.

Tsukiko-chan, I am a words person too… it is very frustrating.
