If you drink any alcohol you are finished diving for the day. No dry suits in the cabin area. Dive with a buddy. And after that, do what it takes to have a great time. For me to have that great adventure under the enchanted emerald sea means diving very closely with someone who respects my level of diving and the reasons I want to dive.
People do things for many reasons.
I have fallen in love with diving as it opened another dimension of the earth to me. It opened a world called the sea. It opened new vistas and scenery beyond compare. I also dive for the sensation of weightlessness and the relaxation of the deep breathing one must do to survive. In warm water I would be considered a fairly good and independent diver.
