Re: Allergy to Coconut Oil?

Since it happens while you are reclining, it sounds like Gastroesophageal reflux disease (GERD).
Some people with gastroesophageal reflux commonly report poor sleep, waking at night because of acid reflux. Some individuals who have respiratory problems exacerbated by acid reflux may frequently be without symptoms of heartburn.

It backs up into the esophagus giving the feeling of fullness and pressure in that area.
