The science I was referring to, based on your personal experience, was what happens when you drink.
Change will happen when you decide that the last drink you had will be the last one you will have. There is nothing good about that next drink. No relief, no relaxation, no escape. Nothing in that glass but more of the same.
There is good news, and that is you can stop. You can do it any time. Including Wednesdays. Now is optimal.
