Well, not neuralyze, per se, but there are other means of memory modification in the multiverse. You could use a Memory Charm from the Potterverse, for instance, or find a helpful psychic to remove the unwanted memories for you, or take a trip to any sci-fi 'verse with memory-manipulation technology.

And of course there's the PPC's Department of Fictional Psychology, which has all three of the above standing by at all times. {= )
