Hi justhadenough,
I found AVRT almost six months ago. I think that there should be no need for other books since when we do the Big Plan it is final. We have all the tools we need.
Jack said to me that it is AV if I look for other forms of support since it means we aren't secure in our abstinence. Is there any doubt that you will never drink again? I know for sure I will NEVER drink again, and I mean it. Why would you need more? I'm popping in here now and then because I do like to let others know AVRT really works and not to get any support for myself. I'm doing great and I want others to be as lucky as I was to escape that hell.
Also I think it's best to keep things simple, mix too many sources together and you may end up backsliding. Go and speak with Jack on his site if you need more help.
