Turning pain off might be too extreme.
How about,
"Wait a nanosecond...
this bodily conflagration is burning my flesh.
Hey, I don't like that feeling."
This brings to mind how much pain is needed to be pain,
may be only recognition of a thing is to be reacted to as if it were pain;
or is Reaction to pain what you are seeking to avoid?
As for general changes being hard to deal with
simply program automatic settings
for predetermined situations/environments
(or split second reminders to occurr at those times, as you suggest).
Perhaps I am over simplifying
or talking about an other thing?

Practicality:
If you can't see it you don't know it exists,
so don't worry.
Optimism:
If it can't be fixed you're wrong.
