Well it's prob not helping you want to quit if you live with another stoner. Why do you have to quit anyway? Ultimately, it's up to you bro, if you have to quit, then you have to make it happen. No one can help you but yourself. The only advice i can give you is just suck it up and go cold turkey coz it sounds like you need to. Focus on your family and friends and things you enjoy. Music, food, sports, woman. Books maybe? It;s gonna be tough coz you're gonna be thinking about it all the time so try and take your mind off it as best you can. Get off this site, coz talking to stoners is gonna make you wanna blaze.
