Hi CAVU,
How are you doing? Are you still experiencing dryness? If so, ask your Dr to switch medications.
I, too, was on Nexium, but experienced abdominal pain/diarrhea as my 'side effect'. I've since been prescribed Zegerid, which is working very well for me. It's a PPI in powder form, you mix with water and take it.
Hope you are feeling better!
Toni
