Yes, I also suffer from PTSD, although in my case it is not related to my military service. Too, I am fortunate in that it is relatively mild and mostly confined to loss of sleep and the reliving of the events that created the problem. It did however, cause a very big change in my attitudes relating to those who were responsible (negatively, of course). Beyond that, I do not choose to discuss the matter.
As for means of dealing with it, I would rather leave that discussion for a PM.
