I'm willing to bet my career that her stories about drinking a whole bottle of whiskey a day are horseshit. I'm a fifteen stone bloke, and put it this way, I like a drink. Just the smell of even the nicest whiskey burns the hairs off my a, and a couple of shots of something like Bells would literally make me puke.
Many years ago, I lost a very dear friend to drink. She was a very petite girl, and she didn't even touch alcohol til after she'd left university. Her poison was Southern Comfort, mixed with lemonade in social situations, out of a pint glass by herself. She was hardcore. She woke up at 6 o'clock like we all do, but instead of eating, she drank alcohol. She held on to her job, but her drinking ruined the rest of her life. She became a liability to be around, and a deeply untrustworthy and devious person in her pursuit of the only thing that mattered to her: Alcohol. By the time she was twenty eight she looked like a walking corpse, and was told by her GP to stop drinking or die. She weighed about six stone, she began to suffer from psychosis, and her liver had already given way to hepatitis. She died from a scarred liver aged just thirty. Her mum died a few years later from a broken heart.
Jack is an attention seeking fraud and buller, who thinks stories like the one I just told are cool and trendy. That's her speciality: Edgy bleeping stories that she's completely unqualified to talk about.
