how long does each dose last?

[Guest guest]

i get three shots of xolair every two weeks. i'm due to get my 9th

dose of xolair this thursday. i'm finding the last dose or two that

i really am feeling better. the week after the shots i feel

fabulous...as the second week begins, i feel a bit worse again,

having more allergy symptoms (watery and crazy itchy eyes, twitchy

lungs, eczema bothers me a little...) and my asthma takes a small

dip. i also cut back on my flovent (from 2200 mcg (5 puffs a day of

flovent220 twice daily)to 1000 (advair 500 2 times a day) in the

last two weeks)

does xolair wear off? am i imagining this? is it just coincidence

with the weather??? am i crazy???

thanks
