Puking is the only thing that works for me.
But I like the ice pack idea. Then I have something to vomit in

Hey Spartakus:
As you see, there is no such thing as a fix all for everyone. Well, there is one idea and that is to abstain from boat trips but then again, we are talking about the fun stuff of scuba diving.
I will toss in my experiences with Bonine, Dramamine, & ginger. All work for me. I take the Bonine or Dramamine about three hours before departing the dock and all is well. If I took ginger, it would be in the form of either ginger snaps or ginger ale. Those worked for me tool. Of course, I didn't religiously take something before a trip. I listened to the coastal marine forecast because as a mate on a diving boat, I couldn't say I wasn't going out because I thought it sounded bad. That was the customer's and ultimately the Captain's call. If it's occasional 4 foot seas and a group wants to head out and the Captain could go either way, well I'm with the Captain. I did get sick one time because of it and despite my pre-planning, but to my later joy, the Captain admitted he didn't feel good either during the trip. The moral, my remedies will not protect all from no matter what sea sickness.
Another thing you might try is low dose Benadryl (diphenhydramine HCl) in 10 milligrams. Sure a side effect is drowsiness but at this low dose, it may not bother you any more that other commercially available remedies. This dose is approved for motion sickness but better to take it during a non-diving day just to see how you feel with it.
And rgiles mentioned a transdermal patch; I wonder if it's Scopolamine? That works for some, it's a small patch that is placed behind the ear and stays on for days. I used these when I was in the military during long flights before airborne operations. It worked good for flying but I never used them for boating. I thought they weren't available anymore. Hmph!
Experimentation is your best bet but unfortunately it may be at the expense of getting sick a few more times. Working on your sea legs will help a bit too. Good luck with your solutions and whatever you find that helps- stick with it!
With kind regards,
Thomas
