Aaahhh. Gave in and took a puff of albuterol. It really helped, but I am trying to use it sparingly, as that is the last of my prescription, and I am one of the uninsured. (Well, I got dental, so that's something.) I suppose the is always Primatene Mist, but I've heard that the side effects are less pleasant than albiterol.
Oxygen. Nummy.
