Gurgling?

I've been noticing a gurgling in my throat lately at night. That's when I have the worse symptoms so could it be from the reflux?

Also about an hour after I eat, I'll lay propped up in bed...like in a recliner...and my stomach grumbles and rumbles really loud and my nausea isn't as bad, still there but as tolerable as it can get. When I had the lactose intolerance test the instructions were to not lay down after drinking the milk because it can affect the digestion. I wonder if that helps digest faster?
