WELCOME to S.R. your g.f. is lucky to have you even tho there is no magic portion for her. the only thing you can do is continue to tell her how proud u are of her. you can not keep her clean if she really wants to use she will. the longer she stays clean the easier it willl be for her. it takes yrs for some to get over the cravings & others never get rid of it. she needs to go to meetings & find a sponsor but u can not make her do that. pray for her & i will say a prayer for both of you.
