Mike, SR is in your corner, we all want you to beat this!!
For me I needed to revolutionise my lifestyle, are you simply trying to not drink? I found I needed to do more than that, I needed support, new activities, not just sit in my house with my thoughts, that usually ended only one way!!
I also needed to really accept, that I'm now a non drinker, no more of these thoughts of moderation etc, I was now not drinking no matter what, because that first drink always leads to the same place.
You can do this Mike, but you need to accept what the solution is to the problem and then make some big changes to achieve it!!
