Welcome.
Read that book. It helps.
Never engage in a battle that you can't be certain of winning.
Your token system sounds good, but clearly your son didn't get it, and thought you were setting up something bad and not something good.
The best way to begin with your son (and I do think you need to start over, to find something that has a chance of working) is to start where he is. Get into his head. Try to see things purely from his point of view. For now. I'm not saying the kid is right and you are wrong - far from it. This isn't about right or wrong, it's about perceptions.
I'll give you an example - difficult child 3. He's got a history of anxiety and stress. He is very good at reading but refused to read a new story or watch a new film or TV show, because the necessary conflict in the story (an important part of any plot) was too stressful for him. But over time we managed to expose him to new films. We showed him a lot of "making of..." special features on DVDs to help him understand the movie making process. When he was about ten years old we had him come with us to a village film night, watching 'Mars Attacks!" We fully expected difficult child 3 to sleep on the floor mats like a lot of other children do on these film nights, but to our surprise, difficult child 3 was watching the screen. part of the action was upsetting him so I kept telling him, "It's not real. It's just a movie. They are actors. The martians are CG, they don't really exist."
I really thought he understood. But after the film when we were all having coffee (and difficult child 3 was once more complaining of nausea, a sign of anxiety) he was pestering me for answers about the film. "All those buildings they destroyed - how dod they put them back up again? It is expensive to make a movie, they have to rebuild all the stuff they destroy. I get that. But how did they bring those actors back to life again after they were incinerated? And did they put the lady's head back on her, and the dog back together again?"
That was when I realised that difficult child 3 was really believing that while actors say lines and are filmed, the bad stuff really does happen to people and places, it is the cost of the entertainment industry. It was to him like the old gladiator fights of ancient Rome. I felt like a parent at the ancient Roman Coliseum, forcing my child to watch people being torn apart by wild beasts in the name of entertainment and telling him to toughen up and learn to live with it. What must he have thought of us! What horrible people we must seem to him... and her he was making a supreme effort to watch the movie and accept that WE want him to learn to enjoy films!
It isn't always easy to see things form your child's point of view, but once you can, it makes it a lot easier for you to lead him from there towards your own point of view.
You need to listen to him. Ask him what he believes to be the situation with your sticker chart. The point should be - he can earn EXTRA treats. This isn't simply a way of limiting what he currently feels is his free right. He might have been thinking, "I get to watch four hours of TV a night anyway. Now I'm only going to be allowed to watch any TV at all after I earn the privilege."
If you can set up the reward system with him, he will feel ownership. You have made your own choices about what rewards to use - why not ask him? He migt surprise you.
A really good reward system we were put on to, is a non-material one. difficult child 3 can earn time - that is time with me, spent playing a computer game. When difficult child 3 earns time, we spend that time sitting together playing Mario Party. The reward is he gets to share something he loves with someone he loves.
Another important thing - rewards once earned stay earned. You don't take stars away or points away, unless you have previously agreed it will work that way. In general it is a bad idea. Instead, if he transgresses then he fails to earn. For example, difficult child 3 first earned reward time for a day with no meltdowns. If he had a meltdown, he simply didn't earn time that day. It was enough - he learned to control himself a lot more, just with that incentive and no punishment.
I hope this helps.
