i've been sober for 14 days now. mod-heavy drinker for 20 years.
i've noticed the following physical changes:
weight loss
less bruises/bruising - i used to bump into things/injure myself a lot more when drunk - obviously.
my eyes are 'clearer' 'shinier' - waaaay less puff in them and in my face in general.
i'd say probably my skin is better/younger looking BUT unfortunately at this time i'm smoking more cigarettes as a coping mechanism (not the best one i realize!)
