Re: After eating or drinking ANYTHING, burping up foamy liquid.
Not to contradict what others are saying, but did the symptome appears only after you started the Zantac with the Nexium? If so, then I would say that maybe it is related to the medication.
I'm on Zantac too (no Nexium), and I notice the need to burp a lot after eating and that the burping relieves the globus sensensation. However, I don't have any liquid come up, so I don't know if what I'm experiencing is at all like what you are experiencing.
Ladybud seems to have experienced your exact symptoms, so she may indeed be right.
