I have indeed gone through this and can relate to your frustration. Some research suggests that periodic binge drinking actually can be harder on your brain and nervous system than more consistent drinking because it's the process of repeated withdrawal cycles that does the damage.
In any case, I never found any magic pill or activity that "cured" me of PAWS-type neurological symptoms. They have gradually ebbed over time (with some ups and downs along the way). As the Serenity Prayer suggests, all I can do is change the things I can while accepting the things I can't. That has meant making adjustments to my attitude and lifestyle so that the symptoms are less intrusive and I'm not so focused on them anymore. It's all in the actions I take, and in how I look at things. Oh, and no caffeine at all for me!
Everyone's different, of course, but at 11 months I had barely begun to experience any relief yet. It was a good 2 years before I began to have more good days than bad ones.
Hope this helps, and best of luck!
