I do that quite often, actually... comes from being tired, and my wife always says you are not supposed to put warm meat in fridge also... one time I was making protein drinks with some skim milk and a brand of powder I never had before, towards the end of the day and two shakes later I was like damn that proteins rough, lol... that night I had big bowl of ice cream and chased it with a glass of milk, promptly spit it back up, shit was rotten the whole time, figure I drank close to 2 quarts rotten milk, didn't affect me at all... one thing I have is strong guts
