Any advice for quitting drinking.

It's not messing up my life by most markers, but i at least have 2-4 drinks every night. I dont go out much anymore (stay at home with family) but i always make sure i have some alcohol handy to get a buzz on. I used to be addicted to hard drugs but i haven't done them in 11 months.

I feel like when i dont have a drink for a day or two my mind is much more focused, but i always break that focus by thinking "i could have a few drinks and study/ write" and then become distracted.
