Sometimes trying to fix it is not that easy ... sometimes you know, you can see, but you just feel like you cant stop. And it takes a long time until you can actually do it. But you will, eventually.
Big hug!
I know how you feel to a degree. I struggled through a lot of my life with ADHD. But it was never diagnosed as a kid. I figured it out over the years and have worked to overcome it. I finally went to clinical psychologist at the beginning of this year and was officially diagnosed. I don't want medication yet, because I don't want the personality changes that may come along with it, as well as the cost of having no medical insurance here in the US.
Many alcoholics are simply self-medicating for larger mental health issues like anxiety, depression, or bi-polar disorder (like my sister did for many years). If you feel the need to drink so much, then you may be battling a larger mental health issue. The stigma's that used that used to exist on people with mental health disorders have significantly declined as the medical science has become more and more concrete about their existence and the ability to overcome them with simple medication or through support groups.
I hope you find what you need to overcome your struggles.
(Drinking is not a problem itself, I love a good beer, and like to get drunk every now and then with my friends. But compulsively drinking or drinking on a regular basis to escape our pain is a sign that you may need help)
Big hug!
