HI, thanks for using healthcare magic
The symptoms are in keeping with your diagnosis if GERD.
GERD can cause burping, regurgitation,
nausea, burning discomfort in the chest,
cough, acid or bitter taste in the mouth.
Some or all of these may occur.
Continue restricting the foods that can aggravate the problem this includes caffeine, mint, tomatoes, onion, citrus fruits,chocolate.
Use small meals ,
weight loss of any excess weight is also helpful
You may want to ask your doctor whether the dose of
nexium can be adjusted to a higher dose for a short period of time.
I hope this helps
