As far as I know meds are the only way to remove hallucinations and since they aren’t OTC that means doctor. There are ways to learn to tolerate instead of remove...sounds like she’s doing a fair job of this already but there are hearing voices groups. As far as the all senses thing a lot of docs simply assume things so they don’t even ask...a lot of people get multiple senses...for me I get all five senses separately but some people get the total immersion thing.
