About 8 years ago, I started getting very bad asthma attacks from food coloring and some creamy dairy, exertion, dust... and something to do with the Japanese trees in the winter etc. I have had to go to hospital a few times for severe ones.
It took a few months after quitting smoking and taking up ecigs to improve, so I didn't think it had improved until I realized a few weeks ago, that I didn't have an asthma pump in my bag, and only because hubby asked me if I had it! Practically every single room in the house and most of my handbags had at least pump, sometimes several. Like for eg. my dog walkies bag, my work bag, gym bag, out and about bag, in the car, next to the bed etc. lol. Anyway, then I thought about it and realized that I hadn't used my pumps for months!! Not only that, I have just passed a whole winter with barely ever using my asthma pumps, when i would have gone through several! Wow!
