Just a quick update for anyone wondering: I've done over 50 dives since the closure, including some in the Red Sea and off Jupiter, FL that I've referred to as "scuba boot camp" between lots of swimming and pretty good currents. :coolingoff: I'm able to dive less conservatively than I used to (in the past I'd pretty much have to stick to air profiles while on Nitrox in order to completely avoid symptoms), and have not had any problems whatsoever. I feel better diving now than I have in years.
