Will 'anti-condensation paint' help
no.

or do I need something more like
some sort of plastic foam insulation.

yes.

I don't want to stick expanded
polystyrene there but some sort of flexible stick on foam would be OK.

anything that has some kind of decent U value...actually you may be
surprised at how good cork wall tiles are.

I lined a single brick kitchen with them once - hell of a difference.

When did you last see them on sale though ?. Very 1970's and now cork
