I suggest reading the Acid Watchers Diet by Dr. Aviv, not eating anything three to four hours before bedtime, walking daily for exercise..I would think hard and clear before doing surgery. My husband had it and he developed gastroparesis afterwards because we think the vagus nerve was damaged during surgery. He has lost 17pounds and he cannot gain weight. I wish you good luck and hope you talk to your doctor about what you can expect after the fundaplication.
