I am allergic to cats among other airborne things, have asthma, bunged up nose, mucus, sneezing, itchy red swollen eyes, itchy red chin- im painting such a pretty picture of myself arent i LOL!!! Anyway i take antihistamines daily but im trying to find another one because this one isnt as affective anymore. Any suggestions? Weve got wood flooring throughout our house with a few rugs that i clean an hoover frequently, ive got inhalers i take daily- is there anything else i can try? I want to try an air filter but would love to hear how much of a difference it makes first? Can you get stronger antihistamines from a doctor? I just would like to hear from other sufferers so i can feel less alone in my suffering!!!! Feeling sorry for myself today LOL!!
