Cap,
I believe we all get about 20 to 30 years of moderate drinking before the brain damage starts to really show through.
You are probably a happy drunk that stayed out of trouble when drinking...or got lucky.....like me.
I quit for 8 months, when i was in my late 20.s, and started again because quiting was so easy. Drank for the next 20 years and started having mental and physical issues.
I quit and started to have horrid anxiety well into my first 2 months clean.
Google search. Found this place. SR saved my life.
My anxiety has quelled steadily over the last 15 months.
Never drinking again. I've drank enough for this lifetime.
