Would it be possible to find work, as in any work what so ever, before you move back in with your parents? It may be good thing to not have access to money, but I feel that isn't a solution is our society. The solution is learning how to control your impulses better which can be a long process. I think it depends heavily upon your situation but I know for myself doing something similar would lead me to relapse more than likely. I think too much free time and no stimuli is worse than working a job you hate. Even though you hate it, it does offer a small amount of networking and contact with people other than yourself and some money, although perhaps minimal. I think a better option would be to start putting out applications before you quit your current job as being "currently employed" seems to look better to possible future employers than "currently unemployed".
Even still, a crap job is still a crap job and beyond keeping your opportunities open, it may be a good thing for you to quit your job. I just recently quit a decent paying job after getting clean because I felt my patterns of addictions were also deeply rooted in my 'addiction' or strong drive to make money and work- I suppose workaholism. For me, I am a 24 year old single male and I have enough saved up to where not finding work for a while is not a huge worry, as well as have quite a few opportunities to work if I so desired. The important thing was that I not get completely consumed by work and money, then start using drugs to cope with the stress and isolation that comes with working a lot.
People usually advise against going cold turkey because of the much more intense W/D symptoms you will experience, making it much more likely for a relapse to occur. Having some type of mild opiate or benzo on hand, in a very small SMALL amount and quantity for when you are experiencing panic-attack like symptoms or feeling like there is no hope and the world is collapsing around you--- you know those types of feelings that make your mind focus on using again.
I think a taper when used correctly can assist someone in helping to break the habit of getting completely wasted every time discomfort is experienced. Instead of getting high you give yourself just barely enough so you can focus on something else like a productive task or whatever it may be.
