If steam helps, let me suggest getting a Jiffy ESteam travel steamer--I got one because I was tired of ironing clothes in hotel rooms, and realized that it helped loosen my cough while I was using. It's much more portable than any of the "Therapeutic" steamers, and actually generates more steam than most of them--and you'll always look your best!--

It's about two thirds of the way down this pageJiffy Steamers I pasted a UK link, but you can get them just about anywhere in the world. In the US they are considerably less expensive--
