Two weeks ago, all of a sudden. I couldn t get rid of my dry throat. I have been drinking water and have a sticky, dry feeling even while I m drinking. Now mouth is drying and I don t seem to be producing a lot of saliva. I do however if I eg. Chew gum. My eyes have started getting dry a few days ago with the dryer mouth. I do smoke, I usually have 3-4 cups of coffee a day but recently I ve been drinking 2-2.5L of water a day thinking I may be dyhydrated! I feel tired, muscles ache especially in my neck, I have had stomach reflux for a couple of days. Hopefully you can help?
