Well
I am now on dive 12 or so. I had problem once with pressure equalizing going down, other than that no issues at all. At this point I am sleeping in the chamber, and, yes they wake you up for air breaks. Is it working? The one thing I have noticed is that my gums do not bleed anymore and I can use the toothbrush more vigorously. Also, I have a lot more energy these days. It is not clear whether this is due to the treatment, the sleep I get in the mornings or the other stuff that I am doing now (supplements).
