@bibliolater If your well trained its not so scary ... i promise.
@freemo Can the training overcome claustrophobia?
@bibliolater I would think so. When I started diving i was extremely scared of deep water. Took me about 10 dives post training before the fear went away. I'd imagine the same would be true of cave diving.
@freemo @bibliolater A beta blocker might be beneficial because of the reduced adrenal response. It's not going to stop panic but it should help with the physical symptoms.
@freemo The caves without breathable air are instant death for free divers. It still sounds fun though and there are worse ways to go out.
I really enjoy cave diving.
