Thanks for all of the suggestions and information y'all!! Madamekelly, thanks for the nasal spray suggestion! I'll have to try that. I've tried sucking on a piece of hard candy while cutting, and that seems to help with the coughing a bit, but I was still sneezing.
I've also tried the dust mask before while sanding down furniture to refinish, but for one thing, I feel like I'm suffocating! Another problem I have with it is that no matter how I try to adjust it, my breath will sneak out of the top and steam up my glasses! It's kinda hard to cut fabric looking through a thick fog! LOL!
