She described her stomachache as her digestive system is completely whacked, she stated that she also dropped 10lbs she thinks, maybe because she was not getting enough food. She tried to eat some meat on Saturday, she have not gone to the bathroom since then, and her stomach had not stopped hurting also since then. She had a pancake yesterday and a teaspoon of oatmeal. Her gut feels like the vaccine went against her and started attacking her gut. She did took Tylenol for medication, because she thinks she needs to do something about these side effects.
