First I have to say, I have never used the program- but I have to admit I giggle a little whenever I hear the commercial. I think these types of programs prey on parents who think there is some kind of "Magic" cure to fix their teen/pre teen, and it's all common sense that you probably already know but are not consistant in using. My kids are now in there twenties, when they were teens, we were involved in many diff. programs including one called "tough love" which is probably an extreme for what you need. But basically the idea is that you say something, you stick to it, you do it. With teens/children in general, empty threats don't work- they must know you are serious or you will get no results from them. Keep in mind that even though you don't feel it, you are in control of all the cards... once you truely believe that you will be very surprised how they listen. Do not argue with them, say what you need to say and don't debate them. Your word should be the last one, remember something that I learned along the way... when you are working do you debate your boss? no, you just do as your told, there is no debate his/her word is usually the last.
Get control of your child now, trust me it get's worse if you don't. Good luck, I wouldn't waste your money on those programs, just do what you already know- just do it consistantly
