Jane Lynch, 51, better known as Sue Sylvester, the gym coach on Glee has revealed in her upcoming biography Happy Accidents how she used to drink bottles of NyQuil syrup – an over-the-counter medication that aims to relive symptoms of the common cold – when she stopped consuming alcohol in 1991, aged 31, due to fears she was becoming dependent on booze.She wrote in her book: “I found myself eating about a gallon of chocolate ice cream daily to replace the copious amounts of sugar my body was used to from my daily beer intake. I did, however, continue my habit of taking NyQuil before bed. Though no longer drinking Miller Lite I was in need of something to soothe me. the fact that NyQuil had alcohol in it was not something I acknowledged at all. I still considered myself on the wagon.”Jane admits she used to be constantly “miserable” when she was addicted to the substance during a 10-month stay in new York, where she was starring in a play entitled the Real Live Brady Bunch.She wrote: “[The show] ran for 10 months at the Village Gate, and I was miserable the whole time. “I’d close the drapes, take a swig of NyQuil, toast with a simple ‘bye bye’ and go into a deep sleep.”Jane – who is married to Lara Embry — eventually found help for her substance abuse problems at Alcoholics Anonymous and she made the decision to go after one evening where she got high with her Brady Bunch cast mates. She writes: “I smoked myself into oblivion that night. I still felt like crap and even lonelier than I had felt before.”Even as the tough talking, overbearing, bullying Sue Sylvester, she can’t mask her loneliness and insecurity, dontcha think? Kinda sad, right? She feeling like a loser. at least, she has fun making fun of Teach Will Shuester and his gang.
