Anyone experience this regularly? Not pregnant, blood tests not indicating menopause although I know these aren't that reliable, they will be repeated in 6 weeks time.
It's not metallic, can sometimes be a bit sour but it's more chemical, like if you lick moisturiser off your lips! I've had it on and off since January this year. I've had a gastroscopy which was normal so no need for ppi's although I do sometimes get a bit of heartburn. Been treated for oral thrush even though swab was negative. Feel like I've exhausted all obvious causes.
Any ideas or remedies?
