Can you elaborate please?
Thanks for the info.
Have you been diagnosed with acid reflux by a doctor?
Does the foam taste acidic?
Do you get this at nights as well?
It sounds like your symptoms are due to your reflux disease which is exacerbated by certain foods or drinks such as carbonated drinks.
This condition is not life threatening.
In general majority of GERD symptoms should be treated with different classes of medicines such as Nexium and diet modification. So you should try to avoid foods or drinks that worsen your symptoms. If all else fails then surgery is also an option to cure GERD.
