Anti nausea advice

Hi all,

My doctor wants me to do an endoscopy/stool test which means I would need to stop taking my ppi for two weeks

I tried to stop taking it and got really bad nausea and was unable to eat. Antacids help with the stomach pain but not with the nausea.

Is there anything I can take to help with nausea/vomitting so I can try to stop my ppi?
