Get some of those tears in the bottle things, they make all the difference in the world for comfort level - - and might also prevent damage to the eye due to lack of lubrication. We produce tears but the oily stuff that lubricates is what is not being produced. You can buy them over the counter, but be sure they're artificial tears, not just plain old eye drops. For dry mouth drinking lots of water is about the only thing I've found useful.
