A few people have suggested my EIA may of gotten worse from some triggers or food allergies. I wouldn't be surprised if that was the case. I guess it must be hard sometimes to figure out what that is. If in fact that is part of the the problem trying to figure out the cause. I didn't have any asthma until suddenly about 10-12 years ago. I also found out at about the same time I am allergic to MSG which I used to consume with no problems before that. It gives me migraines. I also seem to get migraines from too much dark chocolate, but some is OK, certain nuts and too much red wine. Who knows what else?
