Bitter Veggie Sandwich Reaction - Subway, Eugene Oregon

2704 Willakenzie Road, Eugene, 97401 Oregon, United States

Subway on Willakenzie in Eugene, OR.
Ate a veggie sandwich a few hours ago (I have been eating the same thing for years, lol, so I would know if this was different from the usual) (contained: Italian herb and cheese bread, mayo, mustard, lettuce, tomatoes, pickles, olives, cucumbers, spinach, and bell peppers). Something was off *immediately,* as the whole sandwich was so bitter that I could barely get a bite down. I tried a few different spots along the food item, but it was the entire sandwich that tasted this bitter - almost more rancid than if someone were to eat very bitter nuts. Regardless, the sandwich is hanging out in my freezer, but I am nauseous, vomiting, and my stomach is cramping big time.
Review: 2/10; would definitely still go to a different subway without an apparent existence of ingredients having spoiled. | Symptoms: Nausea, Vomiting, Stomach Pain, Cramps
