You can do it

It has been two days since we have been aboard this ship. Yet up until now, I still feel seasick. The sailors, the knights, my servants, and even brother Seymour said that seasickness would only last for no more longer than five hours. 

But how come I am still seasick for two days?

"Urck! Urck! Urck! Cough, cough, cough!" I barfed as I felt an overwhelming nauseousness. "Urchk! Cough! Cough!" I cannot stand this anymore. Why did I even agree with brother Seymour to go and travel with him to the Kingdom of Balker. 

Worst case scenario is that we are on a ship, and I cannot even take a good nap! Everything was moving. Everything was unstable. My ears kept on ringing, and my body— especially my shoulders. They feel sore and stiff, and so are my hands and feet.
