Hi spiriteyes
That was never my strong point either....three days after I 'quit for good', I'd always be back at it.
Eventually I got myself in real trouble....the sooner you can break this cycle the better in my opinion.
I don't know whether this strikes a chord with you, but I think a large part of my problem was I didn't want to quit, I simply wanted to control my drinking.
I had to accept that simply wasn't possible before I moved on into recovery.
