How many units of alcohol do you consume in a week?

I don’t really touch alcohol anymore and when I do I realise I just don’t enjoy it these days. I’ve spent the last 10+ years watching my step-dad drink his life away. I know some people drink a lot more but he’d throw at least 8-15 cans of beer down his neck in an evening. He didn’t often turn nasty or aggressive but I watched this absolutely wreck and destroy his relationship with my mum whilst also watching him start with health problems and refuse to admit it was drink induced. I think that in itself has put me off. But then last time I did have a few drinks which was last September, I’d never felt so ill in my life. And when I looked at my empty bottle of whiskey, I just felt more sick, and thinking to myself that I’ve just poisoned myself. I’ve literally drank poison. And for what? What did I actually gain from that? Apart from a raging hangover, lost most of the next day sleeping it off and starving myself because I couldn’t stomach anything. Same happened a bit before that when my girlfriend went on a night out, she came back that night, hugged the toilet all night, and I was close to ringing an ambulance she was that ill. I haven’t quite written it completely out of my life, I grabbed a few bottles with the recent heatwave to enjoy but they ended up getting opened, few sips, didn’t enjoy it and felt bloated and disposed of the rest
