Not sure if this will help, but I was in a similar place as you not to long ago (3 months). I, too, got to a place where drinking no longer provided me with any benefits. It used to make me feel good and I enjoyed it very much, but slowly but surely it became less and less fun. It got to the point where it was not only not fun but miserable. It started causing problems for me mentally and physically which I ignored for a long while. It got to the point where I said enough is enough. I'm finally starting to feel good about myself for the first time in a long time.
If I can do it I know you can.
