try eating several small meals instead of three large ones whenever you can...Avoid foods that irritate your stomach, especially those that are spicy, acidic, fried or fatty... avoid coffee,tea etc... Avoid stress,consider calming activities, such as meditation, yoga etc...sleep with head raised position and have dinner at least 2 hours before sleep...Consult nearest psychiatrist as you require detailed counseling session and you may require medications to solve your problems as many things can't be discussed in forum like this...good luck.
