Seasick? Is it worth the possibility?

Now we have the opportunity to be a part of a family charter of a boat to go deep sea fishing at OBX for the whole day. I have never done this, but it has definitely peaked interest in me.
My question is-
Will the experience be worth taking the chance of me getting seasick, and barfing my guts out all day?
Opinions more than welcomed. Experiences of such adventures also welcomed.
