Exceeded NDL by a bit, but computer cleared me. What should I do?

But at 20 feet though?

I like the "ear" theory the best for your situation. Any disparity of pressure between one ear and the other is bound to cause balance issues which could make one wobbly. This is especially possible if there are any sinus issues, like mild congestion. However, I am not a doctor, nor do I play one on TV. We look forward to hearing what your diving specialist comes up with.

Would explain everything but mind fog and leg weakness.
Maybe I was just tired or dehydrated. Had 4 hours of sleep

I did a 3-hour single tank dive off of Venice Beach Fl looking for sharks' teeth. I found 708, but I certainly had a hard time getting out of the water. I want to go do it again, except on my rebreather. Vicious 15 to 20 ft depth dives are awesome.

Diving while exhausted is an absolute no-no for me. I will call dives and have.

What should do better next time, apart from monitoring my computer closer next time, and perhaps start Nitrox diving?

Both.

@kaylee_ann, not to hijack this thread but look up biphasic sleep...

Adrenaline is a funky thing- I didn’t feel tired at all. Too nervous and excited. But I know 4 hours wasn’t enough.

That’s cool. I’m doing that right now- just started first shift and am used to being a night owl

Did you strap a spare bank bottle to your back? 3 hours... I'm lucky to get 1.5 with my 100 barely moving in 20 ft

You know what, I got dizzy in the water before surfacing so maybe that’s it.

I've felt dizzy occasionally when ascending. It lasts only for a few seconds and doesn't happen on all dives. The Chairman is probably right in that it is an imbalance in pressure between the two ears. I've had a reverse squeeze in the past and fortunately it didn't result in a punctured or perforated ear drum. If your dizziness is not due to low blood sugar I would advise ascending slower to see if that helps. If the problem continues see an ENT doctor, preferably one who understands diving.

Was it cold water you were diving in? I dive a local spring, where the water temp is a constant 72 degrees and on a couple of occasions I have come up feeling somewhat dizzy. I noticed it more if I wear a hood in the water. Like your dives the average depth is 18-20 feet, with a dive time of about an hour. I've never had it happen anywhere else, other then the spring.
