"Is it possible to have PAWS and be physical depedent to alcohol at this age?"
many years ago, back in my 20's, i knew aman that died from chirrosis( and i didnt even think that could happen to me).
he was 21.
i heard an as speaker once who was 42 at the time and just celebrated 28 years of sobriety.
so,imo, yes, it is posdible.
