In all seriousness, I feel for you and your DS and I hope some of the advice helps.

I know this is late but wanted to add that my son also had night terrors. I read somewhere on the internet that this can be related to overheating (among other things) and that cooling the child's sleeping environment down might help. It was effective for us, and I particularly noticed that I needed to make sure his feet were cool enough (sleeps with no socks on and feet sticking out of the covers).
