My son is 20, and has recently been treated with drugs for psychosis and depression (zyprexa and pristiq). He tells me that he has had drugs before but isn't addicted to them, and his psychosis and anxiety had nothing to do with drugs. The other night he was up pacing the floor and checking doors, saying that he was hearing things, and he told me it was because he hadn't taken medication, but the other day I found an empty insulin syringe packet in his shorts when I was washing them, do you think that he has been lying to me and doctors, and that his psychosis is part of his drug problem. I am worried that he is taking all this medication and if he is taking drugs, what would that do to his body. Suejayne
