He's always been a workaholic but always drank to excess as well.
He didn't drink every day when we were younger but definitely all weekend and one or two nights in the week.
When I was about 8 he got so drunk he fell in a ditch in the dark. I remember watching my mother hose him down in the shower as he was too drunk to wash himself.
He's been like that throughout my childhood. My parent's bedroom would absolutely reek of alcohol in the morning if he'd been to the pub.
He can easily drink 3 or 4 bottles of wine in one sitting. Sometimes five.
I know, reading that back, it screams alcohol problem. But I've grown up watching it and my parent's normalise it that I really struggle to get perspective on it.
