Well it seems like there have been a lot of medical discussions here lately, and now I've gotta throw my hat in the ring now with it too! One of my good childhood friends just got back from spending 2 years in Irag, and we (friends/family) all notice he is acting markedly different. We're not sure if it's just general change after something like that, or something worse... Anyone out there have PTSD, or have any experience dealing with someone with it? THANKS!
