Actually, now that I think of it.  I had actual hypnotherapy for stage fright.  It did NOT help and I'm totally convinced he put himself into a trance, as we spent about 20 minutes in total silence, with me thinking, "is he asleep?"  Then he made a kind of snorting sound and started talking again.  Hmmm..... Needless to say, I didn't bother going to my follow up appointment.
