Anybody can stay sober. You have to want to stay sober more than you want to drink, it honestly is that simple
And as they say, it's not really the stopping, it's the staying stopped & for that you do need a plan. Whatever works. Mine has been the 12 steps in AA, living those principles as best I can each day, & a comittment to my ongoing spiritual development
There is no magic wand. It doesn't take a special or particular kind of person. You just have to want to do it, that's all
Wish you well
