Dude if the medicine you are on is psychotropic rather then percocet or some other narcotic I would seriously listen to what Chance has to say.
PTSD can trigger at anytime anywhere and without the right meds in your system you could lose it.
If you are having a problem with the med's and the side effects I advise you to see your doctor about changing meds. But do not just stop taking them.
This can lead to a very dark place. I know, I've been there.

BTW, please don't take this wrong, I'm not trying to be an ass, but I have always wondered if there is any truth to the South Park episode about Mormons? Do they really believe that John Smith read the book of Mormon from seer stones in a hat?
