I have been taking 2 squirts per day, per nostril of Nasonex for 6 weeks now. After one week, I noticed that I had 'air-hunger' (ie desire to breathe very deeply and finding breathing unsatisfying) and the urge to yawn repeatedly. This has got worse up to the current day and I have found that I have to stop using Nasonex as breathing has become distressing. Got checked out by my doctor who says I am physiologically ok.
