Hello and welcome. You'll find lots of support here from people who have successfuly quit, and those still struggling.
What works for me, and I was a bad drunk, is to remember how I felt after drinking. The following day, the fear anxiety and remorse. And those terrible hangovers.
I could never have just one or two. It was all or nothing for me.
It took me a long time to quit. But, I drank like an alcoholic since the first time I picked it up at fourteen. So I had to learn how not to drink. Support groups help many, maybe you should give one a try.
Best to you and keep on posting.
