I'm the same with drinking i know when i have had enough... Young children tend to drink because of peer pressure. I know I did.. I think no one can control have much there drink... we always think we know when enough is enough but not all the time..

I always think when people litter, do there litter in their own home? No, so why do it in the street. Every where you go now a days, their is litter. As for the enviroment, what are people going to do in 10 years time blame others and not themselves. Littering is bad and can have lasting affect not just today but in the future..
