allergic rhinitis
"I'm 49 and have suffered from allergic symptoms ever since I was a kid. Unquestionably it has reduced the quality of life. Anti-histimines were basically ineffective although I could significantly reduce my symptoms by a strict diet that was in the making over the last 30 years by observation (try eating foods high in anti oxidants). I do feel much better since taking Singulair, my nasal congestion is much better, feel no side effects. My only regret is not trying it earlier."
