Are you a guy or a girl...if female estrogen levels can change over time but you can supplement with estrogen. Being female always gives you an advantage with sz.
There are a couple of weird meds that treat sz but are ridiculously experimental not in the sense that the medicines haven't been approved but in the sense that they aren't typically used for that purpose. So one is warfarin...as part of an unrelated study 5 people with sz stopped hallucinating when being placed on warfarin for other reasons. The other is famotidine which is Pepcid which is an antihistamine like all other a anti-psychotics...the dose needed for Pepcid is much higher than for heartburn because you have to get enough across the blood brain barrier. This is just an over the counter med but something you should discuss with your doc if you want to try it because neither of these meds has really been officially tested for sz.
Here is a link about it....
