About 4 weeks ago I started to get a bad taste at the back of my mouth. This started out of the blue. An internet search made me think acid reflux, as I also get stingy throats. After an online appointment I was prescribed Omeprazole 20mg, and advised to take Gaviscon as well. I have been on this for 3 weeks with very little improvement. I have read other threads about acid reflux, but nothing about the bad taste, which happens several times a day. It is a frequent reminder that something is wrong. Has anyone else had any experience of this please? I am very concerned about this.
