Does anyone else have issues with dry eyes? Feels like I have slept with my eyes open when I first wake up.

This has been going on for a while now. On bad days it feels like am as dehydrated as if I had been out drinking all night the night before... I am guessing it is a mix between hormones playing tricks on my body and the need to hydrate during sleep as well as during the day - although I do drink at least once or twice a night from a small water bottle, but obviously it is not sufficient... I wake up parched as a sand dune... Has anyone else noticed that?
