Hi James,
Have you try getting busy doing something you actually really want to do? Work, house stuff, that occupies your time but not necessarily your mind.
It is only when I worked that out that my attempts at recovery started getting somewhere (like you I am also here trying to quit alcohol but I haven't touched drugs for 6 years).
You can do this, sober up to start with, go through your detox and once your head clears up start building the person you want to be.
Also join the August class with us, plenty of people in a similar situation making some very good progress.
