I used to have GERD (that’s the proper term to use for Google searches) but by doing much of what’s mentioned, it went away.
Here’s my list:
Raise the head of the bed 6-8 inches.
Got a memory foam mattress topper—I no longer toss and turn which tosses the acid around.
Sleep on left side.
No food 4 hours before bed.
I also took chewable enzyme (super papaya) tablets to help digest fatty meals.

To relieve the burn, I found DGL (short for Deglycyrrhizinated Licorice) at the health food store—very soothing.
Another soother is Ginger root juice. Google that and GERD to get the dosage.
Mine’s under control, and almost gone. Between eating less acidic foods, and using lactose free milk, I’m good to go.
