i'm glad to hear other people are coping with this problem! i am also taking a nonsedating antihistimine, allegra, also nasal steroids. i started the shots last week. it's true it is very intense, weekly for 20-30 weeks, then monthly for 3-5 years. but right now i feel like i would do anything to help me keep living with my cats, they are really more like family than pets. this allervax is not like the standard desensitization shots, but i reallly don't know much about it. periodically felix "breaks in" to the bedroom; i think he's really curious about what is going on in there now that he is not allowed. but i think the cats like the newer, cleaner house -- more furniture to hang out on.
