The second shot was on 04Mar2021, and on 06Mar2021, was when she got ill. She went to her doctor on Tuesday and they told her to keep on taking 2 pills like Tylenol 3 times a day. She later stated it was Aspirin that she was taking instead of Tylenol. She did that. Later on, she lost appetite and lost 8 lbs. Her smell was very good, in fact, it was like triple smell.

She went and saw another doctor and that was 16 days of this. She had 4 days of being so weak afterwards. She wanted to take the 3rd shot, but did not want it to kill her. The diarrhea stayed same and she had such terrible cramps in lower intestines. Every time she went to the bathroom, and she went all the time, she would had those cramps. A year earlier, she had a colonoscopy and it was fine. She knew it was because of the vaccine. She initially said it persisted, but later stated it is fine now. Chills felt like bubbles you pop when you get something shipped to you. They weren't there but it felt like it. She did not really register a fever though. It was worse up until that following Tuesday. Then, it did not improve until the following Tuesday, a week later and the doctor asked if she was still having Diarrhea and she told him it quit yesterday. Appetite did not improve right away. She was so weak, she would be eating and would had to put her head down on the table.
