I started shots 2/15 of this year.
It's been 6 months and now I'm at maintenance. I still can't smell all of the time, but I am a lot less miserable.
I was allergic to 36 of the 42 allergens they teated for and I've only ever met 1 other person who was as obviously allergic as me. I'm the kind of allergic that people "with allergies" don't want to be.
I take allegra in the am, singulair in the evening, zyrtec at night, and an inhaled nasal spray because the luquid sprays couldn't reach my sinuses because they were so inflamed.
A friend of mine uses xyzol, it's the strongest one without a prescription, she likes it. I've had multiple physicians tell me that taking as many meds as I take regularly is fine.

I have food allergies, and also am allergic to soaps, a lot of chemicals, pesticides, rag weed, I will not take allergy shots. I eliminated some foods from my diet, no nuts, I eat mostly organic, I also do not eat fried foods, and no meat. I eat sea food about twice a month, organic firm tofu. I do not use commercial cleaning products, I use basis bar soap for my skin, face, body. I use organic coconut oil in a jar as a conditioner for my hair, leave in few minutes rinse out, I do not trust doctors any more. I take Allegra. hope this helps..

See my post earlier today. One of the big 4 is dust mites, when I eliminated them I got some relief,

Allegra worked in my case.

I use strict avoidance of allergens, air purifiers, washing bedding in hot water weekly, zippered cases on pillows and mattresses, avoiding perfumes, and using natural organic products and foods as much as possible. I take benadryl at night. And I am on prednisone for my chronic allergic disease called churg-strauss syndrome, of which Ive been stuck on a 20mg maintainence dose, and I use nebulized breathing treatments. My allergic disease is severe, but anyone with allergies would get relief from the avoidance practices above.
