I agree with Hmtrio2 as that is how you should treat a teenager. Disciplining them is different.
-Negative reinforcement, or taking away something pleasureble tends to work the best.
-Make sure the term of the restriction is reasonable-make the time fit the crime!
-Use natural consquences whenever possible. ie. If they make a mess, they have to clean it. If they break it, they buy it or fix it.
Make sure you have a running dialogue with your teen about all the tough subjects and less dicipline will be needed.
