I have been sick many a time on the ocean.

There is no worse feeling in the world than sea sickness. Been just on the edge of blowing chunks many many times and go up to the bow to get fresh air and some jackazz lights up a smoke near me. I threatened him and was not nice at all about it....

Seasickness really brings out your alter-self...
I remember setting on the bow up by the captains window watching my salmon rod almost snap with a huge chinook tearing line off it and not caring in the world... "F#$& it, who cares...!" This is not like me....

I finally started wearing Scopolomine Transderm tabs behind the ear. A prescription mediction you apply the day before your trip, this helped alot....
Hope your trip went well....
