Hey Andy,
I used to be the same on drink…especially wine. It took me many years and embarrassing/dangerous situations to slow down.
I work in the city in a very demanding role an excellent job but up until about 3 years ago I fucked up loads on corporate events.
I understand your girlfriends excuse / reason and it’s probably true on her part! But honestly she needs to slow down or else something will happen.
My turning point was the day after a corporate event, it was a lovely night out fully paid in Farringdon…I woke up (late) the next morning to a close friend calling me, I had fell asleep and staff woke me up and I punched them in the face… I still to this day don’t remember a thing.
I too had the police called on a few occasions which was mortifying.
Another big wake up call was watching myself in videos and seeing how appalling I acted on wine,
I still drink but never mix drinks or have wine when out and I know people laugh but drinking water every other drink bloody works.
I hope this helps a bit, H x
