What your mind is doing is tormenting you. You know it was cokebut your mind is playing devil's advicate and saying, evilly, "It was v*, ha ha ha". We are our own worst enemies at times. Last week a lady knocked off a bottle of red wine in the supermarket, I saw it as it smashed on the floor and splattered. Thena guy came over with a mop to clean it up.... then my mind started saying "Imagine that was v*, just look, imagine..." You have to try and nip those nasty thoughts in the bud. Hope it helps to know you are not going crazy!
