I had it once from a Krispy Kreme doughnut. My boyfriend's friend worked there and he'd bring us like 3 dozen of the "off" ones. Or ones that were fairly soggy or only got glazed on one side. I didn't like to eat them because I was afraid they would make me sick but I was so ravenous one day that I ate one regardless. Needless to say, I v*d that night and felt unbearably nauseous the rest of the day.
