That sounds pretty extreme! Id be researching how it works, why and what the side effects are. I have pretty bad allergies myself, and Im in the same boat you are, nothing seems to work, and if it does the side effects are not worth it. I got rid of all carpets in my house, replaced the furniture with leather, and bought a dehumidifier to help keep mold out, and that really helped. Im also a big fan of trying to do things the natural way before resorting to meds. I have a friend (who is a doctor) who knew I was searching for natural ways to combat my allergies, and she told me about some recent studies that suggest a lot of immune problems are related to vitamin deficiencies. I started a multivitamin, and it makes me feel pretty good as a general rule, but I cant say whether is helped my allergies because I revamped my house around the same time.
