oh yeah. been there done that.

My DD9 can be very intense with some computer games. Some of the never ending mazes had to be put in the never do again folder. Last summer I took away computer internet games and got him an online writing course that kept him busy. If you can limit time and find other projects/activites that may help. My DD can't play video games for more than an hour. It just gets him too wound up and unpleasant.

good luck.
