Hi John
Based on this thread you and I had / have a lot in common.
I also was a "functional alcoholic", worked, was over weight (wine belly in my case), Christian, felt like a huge hypocrite and tried a few times to quit.
SR has been my main tool for quitting. I could not go to rehab I had a family to run and work to do.
I am 7 and a bit months sober. I am slowly reintroducing myself and my kids back to my old church. I have lost weight and achieved some personal goals involving exercise. This is my next focus.
Exercise and SR chat and SR forums , lots of herbal tea, reading recovery books, continue to help me stay sober. Reading AVRT helped in the early days as well.
Living life sober continues to be challenging. Heck I have emotions I have to deal with every day.
Good Luck.
Your not alone.
