In brief: Thirst at night

The most common cause is blockage of your nasal passages (i.
e., allergies) which force you to breath through your mouth, which is a really dehydrating experience. Other causes include uncontrolled diabetes where the high sugar levels draw fluid out of your system. Diuretics can do the same thing.
