Hey James
I can't give any advice on this - I know that I can't do one drug and not another, but everyone is different.
But to answer your question, yeah there's hope for a guy like you. But it might not be what you were expecting. Read around on substance misuse and alcoholism and see if you can find what you're looking for. It sounds like you want to hear that you can keep the weed, and hey, maybe that would work for you. And there are definitely people here that use dope as a way to get off booze. But most of us find that it's all or nothing and that drugs are a trigger.
Whatever you end up deciding or going with, massive welcome to SR - whether you're using or not, it's good to meet you!
