Thanks everyone. She's still sneezing though not nearly as much so I do believe she's feeling better. My husband wanted me to get liquid Benadryl because he thought it'd be easier than forcing a pill down her throat but she licked at it a couple times and then wouldn't touch it, so she's doing better on her own.

I guess we'll see - if the sneezing picks back up, I'll get some pills and we'll just have to force them down (if we hide them in cheese or lunchmeat, she spits it back out). If that doesn't work, off to the whitecoats...
