Very interesting study on PubMed. It shows that those with mental conditions are low in magnesium compared to healthy subjects. Once put on a pscyhotropic (antidepressent, antipsychotic, etc.), the magesium levels increase. So the medicines increase magnesium, and good magnesium levels show a healthy clinical state.

Great website I came across about all the possible causes of psychosis, including nutritional deficiencies:

i agree with them but instead of it being my mother, its happening to me.. by changing from one antidepressant to the other it can cause a manic mood to be accelerated.. i am bipolar and when my dr thought i was only depressed he prescribed me an antidepressant which only made the manic side 100 times worse.. one of the best things for us bipolars are anticonvulsants.. they dont know why but these seem to balance out the neurotransmitters in the brain for both the depressive and the manic moods.. you may want to talk to your psychiatrist about bipolar disorder.. good luck... =-)
Other than Valium, I don't recognize the other meds. I know my mom is bipolar and she can start thinking several unrealistic things on these medications when she drinks with them. Other than that, I wondered if you have tried the run of the mill anxiety meds, like celexa, cymbalta, zoloft, etc in low dosages? I just know that they always overmedicate my mother because she can get pretty wild with her behavior, and then she's hopped up on these pills that make her worse! Anyway, those are just some thoughts...hope you find an answer. Also, are you going from one psych to the next? Try to find one and stick with them if so, it's just better in the long run to establish a good relationship with them. What about therapy? Ok, I hope it helps:)
