I don't drink daily. I'll usually drink at the weekend (Friday, Saturday, Sunday). If I’ve got lots of social plans then it might be more frequent, but I always have a minimum of two days per week without alcohol.
Max I drink in one 'session' would normally be half a bottle of wine and a whisky, but I wouldn't have that much on consecutive days, quite often I'll just have one glass of wine.
When you add it all up, though, even that probably puts me over the recommended weekly limit, so I'd say that three glasses of wine every evening is definitely more than you 'should' be having.
The key question is, how do you feel if you can't drink for some reason? Do you ever have a day where you don't drink and don't think to yourself "oh I’m not drinking today, well done me!"
If you're thinking about alcohol on a daily basis - either looking forward to having a drink or reminding yourself that you're not going to drink that day - then you've probably got a problem.
