Hi Elisa and welcome to SR
NEO makes an important point. A change in thinking is pivotal to a change in drinking.
You must believe you can do it, just for a day. If you believe every morning when you wake up that you can do without a drink just for today, you have initiated a new pattern of thinking that reinforces itself day by day. At the end of the week, your mind will be stronger.
Fortunately, this move toward change has a subtle domino effect that, as it gains momentum, starts empowering other parts of your life. Yes, it is hard, but sometimes hard can be beautiful.
