I understand how frustrating it is to have all symptoms back once they are gone. I am sure you are following all the dietary restrictions. Avoid spicy and oily food and start regular exercises. Eat at a fixed period and eat light. You can continue on one of the PPI as of now until the symptoms settle down. You can also get your pancreas
tested by Sr. Amylase
and Sr. Lipase
Hope I am able to solve your concerns.
Thanks and get well soon.
