allergic rhinitis
"I suffer from chronic sinusitis caused by allergies.  I also had a bad case of bronchitis a year and a half ago and 3 respiratory infections since.  I have tried a bunch of antibiotics, Claritin D, Zyrtec, Bendryl, Mucinex, Singulair, cough syrups and other OTC decongestants, herbal supplements, steroids, and the Neti Pot. Only the Neti Pot helped me feel better for an hour or so and washed away a lot of the allergens but the sinus inflammation and bronchial irritation due to post nasal drip returned fast. I just started using Allegra 3 days ago and the difference is remarkable.  I can breath again! I also sleep better and I don't feel tired all the time. I have not experienced any side-effects so far."
