Boshizzle, I don't have a solution, but I do feel your pain. There are many meals (after a long smoke) that I just don't enjoy because I have a headache and/or I have inhaled so much smoke that I can't really taste the food. I think I manage my fire pretty well, but hey, when you throw on a new split - there's gonna be some smoke!
Hey, if you think it's a true allergic reaction, you might try an OTC allergy medicine in the morning before you start smoking. Or, pop an all-day pain med like Naproxen for the headache. (Just call me Dr. Feelgood.)
