Excess saliva

According to Murray, a good indicator of reflux is when your mouth is flooded with saliva. Here the same nerves and reflex are involved, just like when you vomit. The body is preparing to wash away whatever is down there.

Swallowing issues

Sometimes reflux can cause a narrowing of the throat because of damage and scarring, so food is actually being held up on its way down.

Asthma

Acid reflux can be the reason for breathing problems. Murray claims:"When you lie down, acid washing up into the esophagus can trigger a reflex that causes wheezing. The acid can also go into the airways and cause direct irritation, so you could be waking up choking and coughing."
