Its the Acid Reflux, Its not something deadly, you just learn how to eat with it. You learn to eat less and avoid certain foods that trigger it.
Certain very acidic foods are really bad and I try to avoid. Potato chips are a favorite of mine that I really cannot eat anymore. Chocolate is really bad and I dont eat it anymore.
Alot of the foods served at Shalosh Seudos fall into those foods that trigger it.
Friday night after a soup I need to wait a couple of hours before eating any other food.
As long as you know these things its not really a big deal
