South Pacific.... Be more Specific....

So I'am sitting here at work, and bored out of my mind..... I'm reading my surfing mag and come across an add for waterwaystravel.com. Awesome site! I want to take a trip out to the south pacific. It will definitely be a boat trip, and then I realize...... I get sea sick. WTF! Now I dont know too many people that have done this type of trip, but should I be worried about being sick? I'am not crazily sea sick, and actually have never thrown up (I just dont feel 100% and really feel like complete d_ck). I have been on small charters in PR, and I went on a charter in OZ, snorkling the Great Barrier Reef which was amazing! The boat was a little bigger and I did not have a problem at all! Anyways I was wondering If I should be worried? I obviously will take necessary precausions and take dramamine, but was wondering what the community here may think.... I just dont want to spend the money and have a bad trip.

Cheers!

Take some chewable orange flavored dramamine along..generic from walgreen's, 25mg.
Works well on rough water..
