Thank you for the information.  I'm going to do some research on it.  You are quite right about it being a rough road.   I worry a great deal about how my son will do if something happens to me.  He depends on me for so much.  I am doing everything in my power to make him independent.  He lives on his own, but calls me many times a day.  He lives in a downtown area that is near to gyms, and a University.  He paints, and is now learning to play guitar.  He also works out several times a week.  It seems that when he can focus his mind on learning things that he does better.  He struggles with being around people as well yet gets lonely.  I keep looking for a support group with people he can relate to - so far no luck. He spends most of his time smoking like a fiend and gets paranoid and delusional.  I will see what I can learn about the swab test because the voices bother him a great deal and the Respirdol doesn't seem to be helping with that.
