Hi Wellington
I'm not in South America but I live in a country where drinking is encouraged and drunkenness is tolerated in many respects too...but my drinking stole my relationships, it stole my health.... it stole my career and it damn nearly stole my life.
There has to come a time when you say enough and stop caring about what other people can or can't do, I think.
SR changed my life - you'll find a lot of support here
Welcome
