The following report from Yvonne Gillham is of interest:

“Dear Ron,

Coming from Hull to here I found that when I started to feel sea-sick and when I indicated to myself that I was PTS and had some SP on my sea track restimulated, it completely blew, and I never had it again.

When I indicated this to Pooky, Thok and Craig it had the same effect on them. I gave the info to Haskell, who was doing review at the time, and he had similar success.

All sickness is PTS, etc, so it follows that sea-sickness would come under this too.

Love,

Yvonne.”
