text: how can a guy i like, quite smokin and drinking alot? it really worries me..?   the only thing you can do is trying to convince him... although i doubt this would make a change... coz almost everyone knows how bad is smoking and drinking a lot. so if he does not want to quit, he won't quit... smoking and drinking can not be controled by anyone but the person himself... do not waste your time. you either take him as he is or leave him...
