There are a great many PTSD sufferers, and there is a desperate need for rapid and effective ways of working with them. Most current treatment approaches are simplistic and grossly ineffective. When I asked an Iraq vet I worked with recently about her previous 5 years of treatment, she said:

I think I saw 8 or 9 different shrinks, and all they wanted to do was give me meds, and then they had all these stupid things they wanted to do, like a tapping thing where you thought about the war and they did this tapping thing, and that was supposed to make it lessen.
