Exclusion criteria
Exclusion criteria: -Surgery of the GI tract other than appendectomy or cholecystectomy. -Use of any medication with a potential effect on gastrointestinal motility, secretion or sensitivity that cannot be stopped for the duration of the study (e.g. H2-blockers, antidepressants, prokinetics). -History of gastrointestinal cancer. -Known diabetes. -Regular use of sleep medication (benzodiazepines) that cannot be stopped. -Severe and clinically unstable concomitant disease (e.g. liver, cardiovascular or lung disease, neurological or psychiatric disorders, cancer or AIDS and other endocrine disorders). -Pregnant or lactating women.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in total nocturnal acid exposure time during pH-impedance studies | — |
Secondary
| Measure | Time frame |
|---|---|
| -Change in number of nocturnal gastroesophageal reflux episodes (both mixed/liquid reflux episodes and both acidic and non-acidic episodes) -Esophageal acid clearance time. -Sleep position during study (supine, prone, left lateral decubitus or right lateral decubitus). -Relation between sleep positions and reflux parameters. -Frequency of reflux symptoms during the night (measured by symptom diary and pH-measurement). -Questionnaires: o GERDQ questionnaire o Reflux Disease Questionnaire (RDQ) score o The Pittsburgh Sleep Quality Index (PSQI) o Nocturnal Gastroesophageal Reflux Disease (GERD) Symptom Severity and Impact Questionnaire (N-GSSIQ). o Global assessment of treatment success. | — |
