"Valium, it shuts down your short term memory. So by the time eight or nine days were in the mix, she didn't know what she was doing anyways.""For years on end, as long as she took her medication properly, she was fine," Anzaldo continued.Chyna rocketed to fame as a wrestler in the World Wrestling Federation (WWF) from 1997 to 2001.She began lifting weights in her hometown of Rochester, New York, at the age of 15, and at one time could reportedly bench press 325 pounds.Chyna was open about growing up in a home with alcoholism and would later have her own documented struggle with drugs.In 2007, viewers saw a different side of Chyna when she appeared on the reality TV show "The Surreal Life."
