Despite all the mental agita, I actually felt good physically for most of the day -- one afternoon reflux episode went by quickly. (At the time, I was feeling frazzled by my ragweed allergies, the heat, and the urgency of setting up our table.)
By the time I was was watching the Mets-Nationals game later, I had no GERD symptoms at all! Even after eating:
1 veggie dog (hurray for CitiField for serving vegetarian options!) with mustard and ketchup
1/2 giant pretzel with mustard
1 chocolate soft serve cup from Carvel's (also in the ballpark)
p.s. After complications from a long course of antibiotics, I have resumed taking probiotics.
