The 3rd or 4th day is the worst for most people and you get slowly better day by day until by the 10th day you are more like
your normal self. The symptoms are like
a bad case of the flu. You'll feel sick and people are different in terms of what they experience--stomach cramps, diarrhea, vomiting, body aches, chills and sweats, sleeplessness, and restlessness in your muscles especially at night when you are in bed. The main thing is that all this passes! And you know what is happening.
