Martin was on this Radiotherapy trial that was supposed to reduce the long term damage to the saliva glands, it's still early days but he still gets the dry dry moss tongue. Apparently the treatment Martin went through was trialed in the US but the results were inconclusive and the consultants there thought it didn't work. The consultants here however think it does. I can't remember what the radiation is called, I got so much information that day that I only rmembered what the things did but not the names.
Otherwise, what exactly is Magic Mouthwash? I asked the consultants who said they didn't know what it was, so i looked for recipes on the internet and found several. I showed them to the consultant who said "Oh no! that would sting your mouth and be too painful". So what is it?
