Welcome to Healing Well! Sorry to hear you're suffering from GERD without much help. It sounds like you're getting some trigger foods that start your problem. Perhaps you could keep a food diary and find a pattern that will help you figure out what the offending foods are.
If you're not getting satisfaction from the treatment you're getting from your doctor, perhaps it's time to get a second opinion. Do you have a GI doctor yet? If this problem is consistently bothering you, it might be time!
Words of wisdom by Eckhart Tolle:
"Whatever you fight, you strengthen, and what you resist, persists.”
“Worry pretends to be necessary but serves no useful purpose”
“Accept - then act. Whatever the present moment contains, accept it as if you had chosen it. Always work with it, not against it.”
