71 year old man, very good general health, not overweight. Recently been having trouble breathing, especially at night....tightness, wheezing, thready thick mucus. When on 2 week vacation, experienced no symptoms. House has 6 cats....about 8 months old. Lots of oak and cedar pollen everywhere. Mild antihistamine works sometimes but dehydrates me.
