I have been on Advair for 3 years and it was a God send. Finally a drug that practically cured my adult asthma. Recently though, I have been very dizzy, nauseated and my heart rate is WAY up (over 100 bpm)--usually after I eat. I have not been able to sleep due to my heart racing all night long. Since you can't get off Advair cold turkey--I'm going to the doc tomorrow. I'm so sad :(
