Why do I constantly clear my throat after I eat? Some days are worse than others, but it s just over and over for 30-45 minutes or so. I have GERDs (I take Nexium in the AM for it), but there s no burning I get with a reflux attack, so I think it s something else. Are there food triggers? For lunch today it was a Dr Pepper , Subway sandwich, and a bag of baked chips.
