Hello guys,
I know that I opened this thread six months ago, but I wanted to give you some feedback regarding all suggestions you guys gave me (and I appreciate all comments).
As I write this, I am in French Polynesia and so far I did eleven dives, from those, I only got really sick in two, and I got dizzy on one, so I am getting there.
Taking Kwells the night before as suggested helped me. I tried a different medication, based on dimenhydrinate (I hope I am spelling it right) but man... it works like a sleeping pill for me... Can't use it!
So, there is definitely the physical factor, but the emotional factor plays an important role. When the instructor that is diving with me is a friendly person and acts in a protective way towards me, I usually don't feel sick. But if the person is one of those "I don't care, just give me your money" kind of person, then I tend to not feel comfortable, so I don't relax and I get anxious, and I usually feel sick... Because I think I will get sick!
Therefore, there are the two components involved.
One trick is discussing my problem before getting on the boat, so when we get there, I am the first one to gear up and enter the water, and on the way back, I am the last person to go back to the boat.
Another trick is to carefully select the dive spot and ask about the sea conditions... And not dive if I don't feel comfortable with either the conditions or the instructor...
I am still to try one of those bracelets or patches, several people recommended them to me saying they work. I will try them and post a follow-up here.
Once again, thank you everybody for helping me with this issue. I feel much more comfortable diving now with the support from people like yourselves.
Best regards,
Gabriel
