Sorry for my lack of recent posting, comp crashed.
I too followed a lot of the behaviour that others have mentioned. Rotating supermarkets to try to avoid the staff recognising me as an alcoholic, and even rotating takeaways when I was drunk so they wouldn't realise. I'm a master of putting on a front, all four of my housemates had absolutely no idea that for 6 weeks I was drinking a bottle of vodka a day and planning to kill myself, the only time they realised that I was even drinking was when they found me passed out surrounded by empty packets of Paracetamol that I had OD'ed on and they searched to find what other drugs I had taken... they opened my wardrobe and empty bottles of vodka poured out. Psychiatrist I saw today wants me to go onto Antabuse for 6 months minimum - I've never gone sober for more than a month since I was 16.
