jeg kan godt forstaa dansk, men ikke saa godt skrive og udtrykke mig selv paa dansk.
i have also been officially diagnosed with schizotypal personality disorder not long after my first psychotic outbreak when i was 16.
and 'pi' certainly had a schizophrenic feel to it.
max was suffering from severe migraines ever since he "looked into the sun".
but those pills he was taking on regular intervals, i don't think it was aspirin.
he was negligent, withdrawn and sociophobic, with a hunch for the inter-relatedness of cosmic events ("patterns in nature").
when pushed too hard by the kaballah sect and the wall street bunch ("survival of the fittest max! and we got the fucking gun!"), he progressed into a full-blown psychosis.
i think that quite fits the schizophrenia spectrum symptomatology as formulated in the DSM.
maybe you've been too long on the crazy pills and forgotten what it was like.

btw, here's a trailer
