hi everyone. im in desperate need for an answer here! im 21 years old, and every night before bed, my mouth starts to get dry. throughout the day it is slightly dry but barely noticeable, until night time rolls around and it starts to bother me. it happens every night like clockwork. Then when i go to sleep, many nights I wake up with a mouth so dry it feels like my whole body has dried out. Its waking me up. This has been happening for over a year now. I drink water all day long to compensate for this, so it cant be dehydration. im lost!
