I get those thoughts all the time. Right after I eat I will get aches because of digestion or just being really full and I will think so hard about the fact that I could V* that I start imagining it and then I feel dizzy and freak out even more, which does not make the digesting part a smooth process. I get the esophagus pains to cause I relate it to ving* but really you are just psyching yourself out. I hope you are feeling better now!!!
