i posted last oct/nov of 2005 and have quite a progression with my 7 year old daughter. in october we decided to take her off of singular due to anger, hyperactivity, chronic illness. she was on at the time singulair 5mg, zyrtec, nasonex, advair 250/500, constant antibiotics and orapred.... and still not well. she was tested for chrones disease due to chronic stomach upset, several ct scans due to recurring sinus infections. we removed her adenoids in december....still sick. i finally took her off all her medication except nasonex, and advair 100 1x a day and had a blood test done called elisa. docs thought i was crazy and said it was worthless. turns out she is allergic to several foods. wierd ones like garlic, onion, melon, bananas, beans etc.....anyway, she is no longer on any of these foods and no longer needs ANY medication....it has been 2 months...we'll see, but there really seems to be something to it. ****** feel free to email me to discuss. we have been through it all!!! hope it helps someone a little. apparently, all those years on antibiotics only made things worse and weakened her immune system which created this horrible cycle.
