Find something else to keep yourself occupied with, surround yourself with people who don't smoke weed, and stay away from people who smoke weed untill you feel like you won't go back to smoking weed! Not sure if this helps, I know a lot of people who have stopped so hopefully its does help! GooooooooooooD luck :)
Find the reason that you want to stop. Tell someone to check up on you everyday and ask how you did. If you know someone else depends on you it's a lot easier to know you won't only be disappointing yourself. :) Good luck. You can do it.
When the cops go over your house.....since your IP Code on your computer leaves you open to that. Try eating a specific candy...my mom got off smoking cigerattes by eating gummy bears...try something to decrease the urge.
