When I left home at 16 I lived with uni students cos my college had no accomodation and I used to get pissed with them all the time. I'd go into college and sleep in my lectures or turn up drunk, I can't remember half of what I learnt. Then I moved onto other stuff for a while but then at the start of the summer this year I started drinking loads. If I was sad I'd drink, if we went to a party we'd drink and when we went out 3 or 4 nights a week I'd drink. I slept all day and I drunk all night and I felt like ****e.
I can't really pinpoint what changed because there was alot of other stuff going on but I drink alot less now. I value my education and going to work able to function. Plus my wallet can't afford constant drinking and I seem to end up doing stupid stuff drunk. I also recognise that alcohol makes me emotional, barely functionable and generally is me sabotaging myself.
If you want to drink less drink less. If people think less of you for it then they aren't your real friends and should ****** off. It's nice to treat yourself, instead of going out one night spend the money you save on something nice to eat/a new dvd and stay in. Alternatively find a friend whose a less heavy drinker and see a film or go for a meal.
