From the start of his second week on the show until he quit, John Tesh was drunk every single night while he anchored "Entertainment Tonight". Oddly, he wasn't an alcoholic. He only drank while in the studio and never, ever, outside of it. He says that he quit drinking completely and gave his notice to the network the day that he thought about taking a drink off the show. He says that the only reason that he drank is that otherwise he would have killed himself on air for "being involved in such an empty waste of time".
