I actually am having this problem right now. Woke up with acid reflux and can't get it to go away. The only things that helped was drinking milk and laying on my left side maybe try that

You need to treat it go to Doctor for heart burn medicine. You can get cancer in esophagus I take medicine now I don’t have acid reflux

Omeprezole does wonders if you take it consistently. I take 40mg daily for my EOE and I rarely have acid reflux flareups anymore either. It’s OTC too so no prescription or anything.

I get acid reflux a lot, especially after I get sick. After I'm sick I try to stay on a mild diet and I drink chamomile tea which helps a bit. Eating plain foods like toast or plain rice helps me.
