That is a shame. My condolences.
A friend of mine, who i dived regularly deep air to 2.8po2 with started to get cold so we switched to drysuits. On a 90m dive (2.0bar) she temporarily lost her vision and this was repeated on a subsequent 83m dive. Some weeks later she investigated being a chamber technician but failed the oxygen tolerance test by developing uncontrolled hiccuping and diaphragm spasm during the test.
The chamber manager recommended she not run po2's above 1.4 in the future because of this. I wonder how many people in the genpop are intolerent to high or prolonged medium po2's? There are indeed many ways to get caught out underwater.
Seasons Greetings

Glad to hear that others have had the same symptoms
Those are not in the books I have read, hiccups and diaphragm spasm. I had those in water and also in the chamber. The chamber nurse did not like me taking the O2 mask of now and then during the chamber run. I just replied that I don+t want to convulse here and bang my head somewhere
