My husband had the same problem. He even got seasick free diving for abalone, at least while on the surface.I suffer from severe seasickness, so being on a boat is a nightmare for me, I do dive, free diving and also scuba diving, and do spear fishing . I have some freinds that go deep sea fishing on boats and in time to time I buy from them some nice fish.
Once under the water he's better. It's lessened as he's gotten older. The over the counter drugs work fine now. We got to go whale watching in Alaska several years ago, and it was fantastic. Got to see a large pod of orcas and 4 humpback whales bubble-net fishing.
