Article in English: When the big day arrives, keep your promise to yourself and quit. Those first few days are going to be hard. Keep yourself busy and stay positive. You're on your way to an addiction-free life. If you need distractions, try exercising, taking up a new hobby, cooking, or hanging out with friends. Joining a new club, sports team, or other kind of community group will help you make new friends and start a new chapter of your life in which addiction is not a part of. Positive social interactions can stimulate the release of neurochemicals which elicit feelings of happiness and satisfaction without the need for drugs. Exercise releases endorphin chemicals like the ones released in addiction, which is why sometimes you'll hear the term "runner's high". Exercise could open a lot more windows for new and improved health and could lessen the blow of withdrawal by giving you something else to feel good about. Stay away from the people, places and things that make you want to go back to your old habits. You might need to construct a completely new routine for a while until the edge wears off a bit. The physical and mental pain of addiction withdrawal is real, and you'll likely start telling yourself it's okay to take up the habit again. Don't listen to the voice telling you to start back up and don't give up on yourself when it feels hard. Every bit of pain will be worth it in the end.   Common rationalizations include the idea that "it's a free country" or "we all have to die sometime." Resist taking on this defeatist attitude. Go back to your list of reasons for quitting to remember why you're doing this. Think about why quitting is more important than staying addicted. Visit support groups and your therapist each time you feel in danger of relapsing. Everyone slips up from time to time. That doesn't mean you should give in and return to your addictive habits in a full-blown relapse. If you have a slip up, go back over what happened and determine what changes you can make if it happens again. Then get back on your feet...
