Welcome to SR, Benat! You did a good thing to find this site.
What I did to stop drinking (~9 months ago, when I couldn't stop "on my own"):
- Found this site and started posting here, asking questions like WTF is going on w/me and alcohol? (No question is too desperate, trivial, or icky for SR.)
- Tried one day at a time to go without drinking. (Didn't work.)
- Took a suggestion from someone here to try AA.
- Kept coming to SR for support, sometimes all day long.
- Kept going to AA meetings.
Both SR and AA help me stay sober, and I'm sticking with both for as long as I can, because sobriety sure beats my so-called life as a drunk!
