Never had symptoms like that in my life. I once heard that Bruce Lee's mind was so fast he could hardly talk.
Hence all the screaming he did perhaps (or mebbe it was Hong Kong Phooey).
A ventriloquist once told me the secret of keeping your mind in sync with your mouth was to say a gottle of geer twenty times whilst drinking a yard of ale.
Try the helpline they are always good with this sort of thing.
All the very best
