Does magnesium help?

Have had gerd for over 7 years now. Nothing we have tried has helped. Currently taking omeprozale 40mg and famotidine 40mg once each daily.. one at night one in the morning.

Been doing some research to figure out what’s wrong with me since nobody listens. Phantom pains, extreme anxiety etc..

Stumbled across research that pointed towards a magnesium deficiency. have been debating trying magnesium glycinate. Has anyone tried this? Has it helped, made things worse?
