Carrot of Hope is a nonprofit organization on the Web of individuals with PTSD, who are trying to pool their experiential knowledge base in order to create a better future for those with PTSD. It's hard to figure out much from their website about what they're about, but perhaps that's just because they're a work in progress.
However, much of the group's enthusiasm seems to center around a "PTSD cocktail," using various chemicals, that they feel -- from their members' accumulated experience with it -- has some beneficial effect on PTSD. Apparently they are both trying to raise money to study the effects of this cocktail on PTSD, and also provide resources so that those with PTSD can take the information to their doctors and/or health care providers, and initiate a dialogue about whether this treatment might be beneficial. Worth checking out -- especially worth sharing with your health care provider, to see if it might have promise in your particular case.
They say that they are "currently taking donations to fund a research project studying the role of the MAO-A enzyme in post-traumatic stress." According to them, "the Monoamineoxidase-A (MAO-A) removes catecholamines (fight or flight chemicals) from the body," and that "studying MAO-A levels in PTSD patients could be a major key in curing" and possibly even "preventing PTSD in the future.
The article on their website about understanding catecholamines is linked here, and th material about the "PTSD cocktail," which contains three ingredients -- Geodon [Zeldox, Ziprasidone] (20 mg); Propranolol [Inderal] (10-20 mg); and Vistaril (25 mg) -- is linked here.
