I was in the same situation as you so I followed the state guide lines the first thing I did was remove all electronics such as T.V., Stereos ,phones ,game consoles. I locked it all up next thing put a keyd deadbolt lock on your bedroom, keep the only T.V., and phone in there. Next remove all of the non perishable food from the cupboards lock it up so only you have access to it now lock the refrigerator put in a small refrigerator in the garage stock it with bread baloney fruit and water. Laeve only 1 plate 1 glass 1 set of utensils. Next buy the cheapest soap shampoo and toothpaste money can buy. Last but not least remove everything I mean everything!!!!!!!!! from his room except his clothes and bedding even remove the door. Do not wash his clothes either!!!!!!!!!. YOU HAVE NOT VIOLATED STATE GUIDE LINES BY DOING THIS. This will really PI$$ him off but it will also show him that you will not let him take advantage of you. If he says anything about it tell him that this is all the state requires you to do and if he doesn't like it GET THE HELL OUT NOW !!!!!!!!!!!!!!!. This may seem drastic but children need to appreciate how much their parents do for them. GOOD LUCK
