for me i use a combination on top of medication (clozapine).

first i bought burnable sage, and edible sage leaves from the grocer. burned the sage around me and places sage leaves at spots where i dwell most often like bed, desk, doorways. Then i bought diferent kinds of stones and placed them around the yard,

I also did what my aunt told me (shes a healing scents/herbs) person. Salt along window cills and doorways. when i did this i heard a voice say "it burns me".

i had a run in for a few months of feeling and hearing them.
