Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
As you describe there is cystic fibrosis
, and due to that you are having problem of bloating
of stomach gradually upto evening and low in the morning.
Cystic fibrosis is an autosomal disease effecting lungs, pancreas
and intestines. It causes thick secrtions in effected regions and cause infections which are not cured easily.To some extent you are lucky that you are not effected in lungs there it is quite unbearable.
In your case by morning all the secretions getting evacuated down, so you can try to keep the intestines empty by having small meals in an intervals of few hours.
Avoid taking spices, junk foods, and oily foods, and also sour fruits.
Wishing for a quick and complete recovery.
