In my fourth year of my PhD on schizophrenia and I'm currently writing up my thesis. I'm procrastinating right now so thought I'd do something useful with what I've been studying.
And no, schizophrenia is not multiple personality disorder.
Edit: I have to get dinner and run some errands. I'm really enjoying this so I will definitely get back and answer the rest of the questions.
Yea, that doesn't sound like a good recipe for mental health. I avoid pot too, after having a particularly bad experience a couple of years ago. Wasn't really psychotic, but my entire body started getting weird sensations and half my field of vision turned red. I can't smoke without experiencing anxiety now, so I've just stopped.
