My wife has asthma really bad and on top of that she's allergic to anything with asprin in it. For those of you that don't know asprin ingredients are in about 75% of all foods natural and manmade. Plus it's in all preservitives. There have been nights where I could blow 800 and she could only muster 250. That was a hop in the Cos and close your eyes we'll be at the hospital in no time night. It kills me to see her go through it but I don't let her see that it bothers me because I don't want her to feel she's a burden. Just don't give up. It could always be worse
