I went fishing on a 50 foot boat in the ocean for the first time. I was fine until I was home 5 hours?

I was on the Gulf. The water was calm I did not get sick until I was home over 5 hours. I now feel bloated and sick to my stomoch.
it has now been 23 hours since I have been off the boat? I am still nauseated and bloated.
I do take blood pressure medicine, I am 28, and also have nerve damage in my entire leg so I take pain meds. Does that help?
