Different mechanism: While reflux may be part of the problem your symptom and response to treatment suggest a different mechanism, such as an esophageal spasm or a hiatal hernia contributing and among others. Follow up with your treating doc so that supplemental tests or a gastroenterology referral will be considered.

Agree with Dr. P: If you are overweight, losing weight is imperative. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
