Forum:Reset Crazy,Crazy,Crazy

I need to rest the Crazy, Crazy, Crazy quest, so I can get the "Eyesight to the Blind" quest from the BoS. I can just go back to an older savegame, because I did this quest over 10 levels ago, and Im not even sure which savegame would be the right one. What are the steps I need to take to reset this quest?
