Welcome Tinzo,
It is difficult but at the same time very simple. The first thing is to put down the drink and promise yourself you will never drink again. YOU CAN NEVER DRINK AGAIN!
All it takes is not drinking one day at a time. Just for today, this hour or whatever you need to do to not drink in the moment.
There are different programs/methods to help you. You'll get plenty of support and encouragement from the members here.
Stand by for suggestions...
