Yesterday, lungs felt almost clear, certainly a refreshing change. Today woke up with congested/tight chest, and coughing up mucous in the morning. Maybe not enough fluids yesterday....or too much salty foods, such as chips and popcorn.
Note: I think it's not so much the salty food, as the lack of physical activity, that has caused mucous buildup in the lungs.
Note#2: mid-day puff of Oxeze feels most effective when chest is congested/tight in the mornings with a mucous cough. Airways open up more after this dose and more mucous is coughed up, thus opening up the airways more.
