Antipsychotics can be injected.

Most people cannot afford orthomolecular treatment and it may not necessarily be covered through insurance.

You can go in to increase meds, decrease meds, switch meds or re-stabilize on a medication dose. When I was hospitalized, someone went in because she stopped taking her meds for a week or two and needed time away to restart her meds and stabilize. I think she stayed 3-4 days. If you voluntarily go to inpatient you have more rights then being state-ordered. You can ask to leave (they will discharge you after 72 hrs), and you have more say in what you will take.
