Dehydration-like feeling next day after exertion?

I have a trick for getting good aim. After tipping my head back instead of holding the bottle straight down I angle the tip so that it is maybe 10 degrees toward my forehead. It seems off but actually gets better results re hitting the target.

 

Definitely sounds cheaper than my solution, which involves a teaspoon, and a cup full of eye drops.

 

I use drops when watching TV. That's when I really notice how dry my left eye is. So far it's just the one eye affected.

 

I don't know about cheaper, it might be. But it sounds easier than the teaspoon -- but I think that's because I've watched too much tv violence to ever think of spoon and eye in the same thought.
