"Why spend any more time on forums and websites that give vague information, scare stories and references to what DP might be?"
Whaaaat????

I like what he says, I think it is pretty good. I like his idea of projecting fear around you. Makes sense to me. But that (what he writes on his website) is what he accuses others of doing "give vague information, scare stories and references to what DP might be".
If he really had a cure to DP, I doubt he would be out to make money like this of those who actually suffer from it. And since he gives no information of hints whatever about his supposed cure, I assume it is a fraud.
But if you think it can help you, why not? I would not take the chance personally.
It is better to be the widow of a hero than the wife of a coward.
