If you already have DB what about The Divorce Remedy. The sequel to DB? And yes 5LL to me, is a must read. It opened my eyes within the first few minutes of reading it. Very easy read and probably wont take you more than 4 or 5 hours I wouldnt think. Your type of situation is pretty much spot on, minus alcoholism, with some of the situations in the book. Might be able to help you find that starting point you are looking for.
I cant give you any advice on the alcoholism portion of this as I dont have any experience, but Im sure that you will find a wealth of information from others on here about it. Try to post often on here so that your thread is more visible and post on other threads too. You never know, you might be able to help someone else as well.
