Hello
I had gone through your question diligently and I will try to help you out in best possible way 
Acid reflux Aerophagia ( swallowing of air) can be manged with certain dietary and life style modifications like
Avoid fatty fried spicy and junk food or carbonated drinks
Have lots of fresh fruits and vegetables
You can take curd, cold milk or fruit juices 
You should not stay hungry, have something to eat at frequent intervals because hunger increase acid production
You can 
liquid paraffin or 
lactulose for constipation
Avoid smoking and alcohol
relaxation exercises to allay anxiety and stress.
Don't lie down immediately after earing something 
If you can provide me more details like your age and presence of any other metabolic illness like diabetes or thyroid and liver disease , I will be able to help you better 
In my opinion you should 
consult a gastroenterologist for an endoscopy and X ray chest to rule out hiatus hernia
Hope this answers your question
Thanks and regards
