GERD during pregnancy?

Ashley
I think I have this...I have heartburn every night and I take tums for it. But some nifhts(has happened twice) I wake myself up coughing and throwing up in my mouth. Every time I lay down it happens.then my throat will be burning so bad from that. I tried another pillow to raise my head up!! Any ideas? I'm 30 weeks today!! It kept me up all night last night
