I was also a weekend binge drinker - 2 or (usually) 3 days of non-stop drinking.
I definitely know that feeling - coming to afterwards.
My last binge ended on December 17, 2007. That day, I called the AA hotline, met with a recovered alcoholic, and went to my first meeting the following day.
In addition to AA, I rely on counselling & my doctor. Many other support mechanisms including SR and family/friends.
You need help, someone to talk to who understands.
You don't have to live like this.
Take care.
