Multifactorial GERD?: Avoid foods ; behavior that delay stomach emptying ;/or relax the lower esophageal sphincter, but you may also need to consider promotility agents additional to your acid blocker drug(s). Consider ph impedance testing to correlate reflux symptoms with what actually gets refluxed (acid, non-acid material), or whether your residual symptoms may be "functional" due to ibs.
