I was wondering if anyone else has this problem. I love to dive and have been diving for about 3 years. I live in Arizona and dive a lot of lakes. A couple of years ago went to Maui to dive, dove Molokini and Coral Reefs it was wonderful, visibility 150 ft, never get that in AZ. My problem is I get sick to my stomach no matter what I do. I've tried diving on a full stomach and an empty stomach. Its not on the surface, we have a boat so most of my dives are boat dives, I am calm not nervous, we descend and everything is fine, look around for awhile, can't really pinpoint what happens. I have been told just do it, if you have to throw up just hold your regulator in and do it. So far I have not been able to do that, I just get to the surface and here it comes. The good thing is after I get sick, I am fine for the rest of the day. Just wish I could avoid the sickness in the first dive.
