From what you have described, it's an obsession over alcohol.
The obsession can be removed because it's simply a thought process.
To change that thought process can be difficult when it comes to alcohol because of the effect of alcohol, it's too easy.
Perhaps some prayer ? and ask, "take it away"....
A strong cup of chamomile tea helps also, not the tea bag type, but the raw product still on the stems, that way it gives you something to do by cleaning the tea off the stems, into a tea pot and voila!
Your new obsession can be chamomile tea for example, and lots of it with no sugar.
If all else fails, keep praying and look for intuitive thoughts.
