More importantly, with conditioning, there's always the question of what exactly are you doing? (Particularly acute in cases of positive punishment like electroshock.) As far as the suggestion goes, well... I cannot seem to refind it, but within the last 2 or 3 years I ran into a blog where the author set up a electric shock apparatus for himself hooked up to some software. His final post said (or he said when I asked, I forget) that he stopped because he wound up training himself to not use it and it was too aversive to put on.
