Bea32,
Acid reflux is not a listed withdrawal symptom, however it is not uncommon among new quitters. Keep utilizing your home remedies, if they fail or the symptom persists/worsens, consult your doctor.
He/she is the best authority to assist you in determining whether this symptom is related to quitting or if it has been masked by smoking.
Hope you feel better soon.
