One Of My Eyes Leaks Mostly In The AMs. Both

One of my eyes leaks mostly in the AMs. Both eyes feel itchy and I sneeze frequently mostly in the AMs. This can be reduced when I use Chlortrimeton. I am mostly interested in your opinion for the cause of the leaky eye and the itchiness. My eyes are not red or swollen, I have no other allergies, I eat whole foods, I keep my home as dust free as possible. I have 2 cats and the itchy eye and leaky eye occurs when I am away from them as well as at home.
