I think many use it as a tool. I used coffee and booze together. Rather like an "upper" and a "downer". If things were really bad then I would use lots of booze to get out of it.
But I do think coffee might be a hard one to fathom. There appear to be some reports that suggest that coffee may actually help. Again how and why might need some refinement.
Personally, I am reducing both to almost zero. Alcohol likely has some very poor health issues - which when your primary fear is getting cancer and then you take a substance that causes cancer, it does seem rather a bit inconsistent.
