@migizii I was surprised to read your post and learn we have two similar diagnoses...Bronchiectasis and lymphocytic colitis. Also, I nebulize and use a vest twice daily and have not had to go on theBig 3, as they are referred to here.....I have done one round of short term antibiotics a couple years ago. I have always been on the 7% saline solution (since being diagnosed in 2017) at Mayo, although the pulmonologist there said previous scans from my local clinic displayed the disease at least 2years before this.....but no one knew what to look for. I eat a gluten free diet and try to eat well most of the time as I believe there may be a gut-body connection, too. Good luck at your appointment and I hope things go well.
