I've survived my 4 OW dives, and I am by no means a natural at this. But the fear is something to be overcome, and buoyancy control can be learned, but I'm worried about my ears. I made it to 40' without a burst eardrum so I must be clearing the ears eventually, but I was always the last one to depth, as I was bouncing up and down, clearing, feeling pressure, going up, clearing, going down, etc until I made it down. I was using pinch and blow only, and since then have read about different ear clearing techniques, as well as trying sudifed (in moderation) and even nasal irrigation (whatever works, I guess). Even checked with a doctor, who said I probably have narrow tubes, but nothing that puts me at risk for anything. So my question is, can ear clearing be learned, or is it always going to be a physical barrier to enjoying diving? And how bad is it going to be when I try for my AOW and have to dive to 100'?
