If you want to "fix" this, stop struggling.
Try to have SI thoughts 200 times a day.
Thinking and doing are different things.
(Reverse psychology? I think not. Reverse psychology is struggling against what
your mind wants to do)
Look at the thoughts as a metaphor. Try to see how your mind is trying to help
you by having those thoughts.

Off hand I'd say your body just wants attention. Most bodies do.
For that there's exercise, sex, massage, yoga, SI etc.
I wouldn't choose SI.
