I've been waking up with dry eyes too. Mine is caused by allergies (stupid weeds in the backyard, and the grass in the yard, and the darn ragweed and cottonwoods)
Also, I sleep with a ceiling fan on. That can make dry eyes worse too.
I dont know if the Copaxone or the Baclofen can cause it. It's possible, might explain my dry eyes being worse than usual.
I just did a Google search. I found a page that has information about a medical trial that was being conducted to see if Copaxone would help people with macular degeneration. They were also doing a trial with the C for people with MS...and another trial with the C for people with Alzheimer's.
The page was updated last month. That was interesting. I thought they were only using the C for people with MS.

I also found another page that lists dry eye as an infrequent side effect of the C.
