Dizziness and Nausea after Fishing Trip

I have been feeling dizzy the last couple of days after fishing 3 days in a row in Muar on a boat.  Not sure if the dizziness is from the bobbing of the boat or is it something else.  With the dizziness there is nausea and bloated feeling of the stomach.  I wanted to see a doctor but Derrick told me that it is due to the seasickness.  Hope that is the case.
