The question for me was why wouldn't I drink? It was so engrained in my recreation and cultural background and role-models and also it was a bloody great laugh. I used to love it, I really truly did.
BUT it was a love that I realised was far too powerful and unnatural and a love that only an alcoholic will ever feel.
My drinking turned into classic alcoholic drinking and I saw how the park bench was the natural companion of an alcoholic. I didn't mind it when i was drunk but when the booze wore off I wondered whether my best friend was really worth it. I was a ranting, swearing alcoholic chuntering to the sky in a drunken mess. I don't remember none of this (I am reliably informed) but I suddenly realised what I had become and reminded myself of. That street alcoholic who you saw when you were little talking to the sky and shouting and ranting to himself.
Peace
