Have a look at this wonderful doctor…into herbal medicines. The herb lobelia can stop convulsions/fits/psychotic episodes on the spot. Watch it all but particularly from 5.00 mins. https://www.youtube.com/watch?v=iPN52Bwup6w I hope my info of this man can help your friend. Maybe you can contact a Shane Ellison www.thepeopleschemist.com as he was a chemist who developed Eli Lilly’s drugs, but then turned whistleblower against pharma drugs. He may be able to help rectify the problem? Good luck for the best outcome….health!!
