Tonight I'm trying superimposing the personality of a loathable ex. It is especially helpful if the ex relationship started out as a big crush.
Also, cognitive techniques: say "STOP" out loud to myself (like Yoshi in Tetris Attack).
Speaking of cognitive, I just took a battery of tests for the CIA. I don't know how well I did, but I probably did OK, except for the one I ran out of time on.
