dry mouth and dry eyes when lying down
Whenever I get into bed at night, my mouth gets extremely dry within minutes of lying down and my tongue sticks to the roof of my mouth. My eyes become so dry that I sometimes wake up in the middle of the night from the pain and have to insert Acular or lubricant (Allergan Refresh Opthalmic Solution).

I am also experiencing problems with constipation.

I am not on any new medication and haven't changed my lifestyle or diet. I don't drink any alcohol either. I am reasonably healthy, apart from having an autoimmune disease of the central nervous system. I usually drink more than enough fluid during the day, so why the symptoms of dehydration ? I am definitely not diabetic.

What could be causing these symptoms ?

Hi Jen
Some auto immune diseases can cause dry eyes and reducing sputum ( xerostomia)
Systemically, Sjorgren's Syndrome is the most prevalent cause of xerostomia. It is a chronic inflammatory autoimmune disease in which the body's exocrine secretions - the eyes, nose, mouth and vagina - dry up. Other systemic diseases such as sarcoidosis, cystic fibrosis, hormonal dysfunction (thyrotoxicosis and diabetes), seleroderma, hypertension, obesity, hyperlipidemia alcoholic cirrhosis, malnutrition and lichen planus are all associated with xerostomia.
