On the day of the vaccine, she had a good dinner and felt good; but the next morning she was very weak and could only stay awake for very short amounts of time. She was in bed and couldn't stay up and this is not like her, she did not like to be in the bed. She got the feeling of tiredness but that passes and she can stay up for longer periods of time. She had to go eat or she gets very weak, she didn't feel like eating in the beginning. It was on the 4th day after the vaccine she would have to get a bowl of cereal all of a sudden or she would feel like she was going to pass out. She never had trouble with her stomach like this before where she felt the need to have to go and eat. She explained she never had trouble with stomach, she never had headaches, and never had a vaccine before.
