Dum . . . Da dum dum!

Seems I have a mystery on my hands. This morning I woke up and my eyes were oozy and crusty . . . again. So I have to do some asking around and some elimination to figure out what is going on here. I've already done some Internest querying, but haven't found a single thing that has eye discharge without being conjunctivitis. My suspicion is that it is an allergy, and I stripped my bed and put all new linens on it and only a couple pillows. Still, I woke up cruddy. Any suggestions?
