Is your mouth - I mean the inside of your mouth - excessively dry? If it is, which the mouth ulcers suggest might be the case, this could be a sign of an autoimmune condition. Lots of us who've had mouth dryness don't recognise it at first. In my own case, I noticed my lower lip was sticking to my gums a lot and I had an uncomfortable sensation on my tongue, but it took me a long time to work out that I was suffering from dry mouth. Also, do you get soreness or even bleeding at the corners of your mouth?

Oral pathologist and they will know what to do to help it and fix it.
