Update: I have reached 50 sessions and only continue to be quite tired (there is a day or two a week in which I do not do sessions), no improvement or particular symptoms so I imagine that the work is done at a deeper level before being more perceptive in a tangible way
Okay, time for my update. Ark and I have done 185 sessions and it has only been in the last few days that I seem to have turned a major corner. I don't know if it is the number of sessions or the fact that I have done two additional things for the past two weeks.
1) Samozdrav gadget. I'm up to 16 minutes.
2) Extended intermittant fasting. That means, I fast completely on Monday, Wednesday and Friday. Eat sparingly on Tuesday and Thursday, and whatever I want within my dietary limitations on Saturday and Sunday. I started doing this to try to heal my stomach which the doctor says has an "atrophied stomach lining". It was getting to the point where I could eat almost nothing without having gastritis symptoms. Even plain rice and a little meat! So now, I can actually eat on the days I eat without getting sick.
Anyway, suddenly I have energy and get-up-and-go. What's more, I have the stamina to actually do stuff for extended time.
I mean, it was just like some sort of switch turned on. Don't know if it was the combo of the samozdrav and HBOT, or Fasting and HBOT, or fasting and Samozdrav, or all three together, or just HBOT... but, there you have it. So, at this point, I'm not going to change anything.
Another update about HBOT. I've started using the cannula instead of any facemask and not only is it more comfortable, I feel like I get better oxygen flow. I hold it in my teeth and really suck the oxygen out of it when I take a breath. Or, I place it just beneath my nostrils and breathe in strongly through the nose and out through the mouth. This has the effect of accelerating the flow. It gives it a little help when it struggles against the pressure in the chamber.
Also, my back issue seems to be greatly - even dramatically - improved since Chu has been working with me using some kind of strange system that she has been learning from France (forum member). France teaches via skype so if anybody wants to know more about it, contact France or Chu and a thread about it can be started.
It really was miraculous. After two sessions of about 10 minutes each, my back pain of about 50 years appears to have disappeared!
I also think that HBOT has helped my back a lot too and put me in the place where trying a kind of exercise would actually work.
