The worst reflux liquid I've ever experienced in my life not acidity not heartburn

I have the worst reflux coming up throat into mouth its coming in like a tap constantly its not acidity or burning? My stomach is really descended and really weird feeling inside, I've had this for 7mthe but it's becoming worse the last 4 days its like a tap I can't stop it its very unsettling, I take ppi and reglan, I have iem to, every time I chew food its back flows back while I'm chewing swallowing and 24 7 after it makes my stomach really descended and bloated, it's not acidity or burning, I hsve bile reflux coming up on endoscopy report but gastroentolgist never really explained what it is and the only medication is ppi
