It's been a three week t-break for me on Friday and I have the same issue, my mouth is always dry and I catch myself swallowing my saliva sometimes, it's especially dry when I smoke cigs. Maybe I naturally, selfconciously want to get the feeling of being high? Who knows.
idk you know how like when your stoned you feel ur cotton mouth u move ur mouth and its like that mulchy sound thats what i have and i drink alot of water ... prob killed my saliva glands lol
