Just one sip of alcohol can stay in your system for 2 hours. The liver bears the brunt of the damage and although some people appear not to suffer from those effects I add "don't judge a book by the cover", best get an x-ray and then judge for yourself. Due to water retention alcohol bloats your skin. Giving that puffy look. A mild drinker heart can be a few beats off normal.
Needless to say the damaging effects are cumulative and though you are fine now there is no guarantee that you will be later. As for you folks that love to party, I know that this little tidbit of information will not stop you from killing yourself slowly, however, it is my hope that you would seriously consider making healthier choices. Well, as they always say in Hollywood after a film production; "And cut." "That's a wrap."
