Hi JSM -- I don't think your body loses all that it's healed. It probably depends on how long you were out and what you did.
I had a 3 week relapse. During it I had one binge that physically wrecked me -- lower intake probably than when I was drinking daily, but sick for 3 days after. Then I went back to a couple of weeks of almost daily drinking. When I quit the last time, I didn't have the shakes or anything like the withdrawal I'd had after years of heavy daily drinking. I don't think I've had PAWS symptoms this time around, but I also got on an antidepressant, so that might have helped with PAWS.
How are you feeling?
