Also schizoaffective (there's (indeed) really/basically no discontinuity in psychoticism between BP-1 and SZ, only the dynamics change a bit, but still quite gradually; only a different severity separates BP from SZ; basically all (functional) psychoses are schizoaffective ).

Nicotine helps. It's neuroprotective and acts (basically) as a stimulant and "stabiliser" (not just improves focus but also slows you down). The effects are like those of an antipsychotic, in many ways. It (also) reduces the activity of an overactive immune system.

What's more: we (BP/SZ) are less likely to develop cancer, even though (which too is already mentioned) we are far more likely to smoke.
