Coming up for air

I've been having trouble with getting my air in and any type of cardio as well; I came from running a huge race in August to now, not being able to make it up a flight of stairs without having to stop and catch my breath. I took a look back at what could be different since August until now; diet, types of food?, then by coincidence my bulk supply of Advil rolled out of my training bag.........Hmmmmm, it was around the same time I started pushing myself that I started on what I thought was keeping in check my strain and pain management program by using Ibuprofin and wondered if this might have something to do with it. I did a lot of reading and research and in a certain percentage of athsmatics Ibuprofen mixed with certain drugs for treating asthma can have dire and sometimes fatal consequences. I stopped taking Ibuprofin and my aches and pains came back but so did my ability to breathe; last Saturdays fitness class was the first time in months that I made it through in a style that was reminiscent of my previous ability. I'll have to see how it goes over the next while, but I also did the chest x-ray, am going for the full meal deal of tests and have an upcoming Dr. appointment just to be sure. Second, coincidently during this search I also started to look at the amount of sugar in my diet and I'm finding it alarming at how much sugar supposedly some healthy marketed foods have in them. So we'll see where this all goes, but hopefully I've found what ail's me.
