I'm sure it is possible.
I know I could have saved myself a whole lot of grief and reclaimed (many) years of my life had I actually quit the first time I ever said: "I will never drink again." (just words.)
I had lots of half-hearted attempts over the years which I can look back on and realize my mind was not truly set on getting sober for any length of time. I'd dry out for 1 to 3 days and go right back drinking because I never thought beyond those short reprieves.
If you are strong in your resolve to not drink and make a huge change in lifestyle you can do it.
Best wishes.
