I was on a personal boat that headed to a dive site as fast (and choppy hard) as it could make it over the swells because we needed to go about an hour and a half to get to the wreck. The wreck at bottom keel is about 89FT but top of tug was less of course. I got there fine, (a little beaten up by the chop) and first dive was fine. However, when I came out of the water to wait for second dive, I started getting seasick (I assume) and I was in the Navy for three years and NEVER got seasick. I tried eating some chips and it didn’t help much, got tank on and flipped backwards to enter, filled mouthpiece with orange Dorito juice and after I fed the fishes, I was perfectly fine for the rest of the dive and the trip back. Mystery.
