My experience is that I was working too hard with the inhaling, exhaling, and huff coughing and felt exhausted also.
I was not relaxing and doing it correctly. It is hard to teach in words, however, be gentle with the inhaling, exhaling and huff coughing.
I bring up mucus all day long it is so time consuming, if nothing else, and there is plenty of nothing else for us with BE.
Are you sleeping on a wedge at night? Hope so, that is very important.
I wake up at night to walk down the hall to release my bladder and then have to clear mucus before trying to go back to sleep.
Mornings we do have much mucus having built up in the lungs at night.
I am doing my best to nebulize twice a day and many times I will do three times a day with the nebulizing of saline. The third helps with clearing just before bed.
I take it you are sending mucus, mucus plugs, specimens into the lab for testing for the infection and the degree of the infection, type of infection and the number of colonies. Some labs are limited in their ability to do get all that information.
We will probably not be able to clear fully, each time, all the mucus build up. That is my belief and understanding.......and if I am wrong I hope someone will respond to this belief and what they understand.
