After 30 years of daily drinking, I finally decided I'd had enough a year and a half ago. Have enjoyed a sober life since. That being said, I work daily at sobriety. First and foremost, I come to SR. I kinda feel it's like a type of AA of a 'new generation'....for ME, anyway.
So, doing it on my own meant reading lots of different stuff...AA, SMART but really, most of all it was SR.
Like others have said, you have to be ready, and I do mean READY, before anything will work. Good luck to you.
