Man, that really sucks. You should try one of those allergy clinics that do weekly treatments. I think they have programs where you can sign up and go for so many days in a row as they try to eventually make you immune to your allergy.
The only reason I know about this is because I shadowed a physician who had a patient with really bad allergies.
Oh yeah, good luck on the sub. I am waiting for my two 12" Shiva MKIV's to come in the mail and then I will have to do some research and see what design I want to use.
