Prevention methods: Includes avoiding certain foods/drinks, planning when you eat in relation to sleep/activity, and adjusting your sleep position. See comments section for a link to additional info. Over the counter meds may be useful, including omeprazole or Pepcid, (famotidine) but it is recommended this be coordinated with your provider as they are meant for short-term use and may be associated with side effects.

If you are not comfortable or unsure about the medication your Doctor prescribed then it is advisable to get a second opinion from a Psychiatrist and Gastroenterologist after you have had a complete physical exam by your Primary Care Physician to rule out any underlying illness. A Clinical Psychologist can also help you with psychotherapy.
