I've been through 90 dives in the hyperbaric chamber and it definitely works. I did 30 dives in 2004 and 60 dives in 2007.I actually needed to have ear tubes first because I couldn't counter the pressure by holding my nose and blowing(like in an airplane). I nearly died of boredom but you do what you have to do when you have what we have.
