You asked about my hyperbaric chamber, which is my lifesaver. Honestly, if I skip about 10 days, I start to feel a kind of toxic-unto-death feeling that is just horrible. One hour session keeps that at bay for about 10 days and makes me feel more whole, energetic, and has done good things for my digestion, and I think somewhat saved my brain
)))).
I have my own home chamber. This is extremely convenient but its also an expensive item. However many chiropractors and holistic docs carry them these days. To find someone in your area you might google around or you can call oxyhealth, the firm that makes them, in California and ask for a referral.
I would highly recommend it. I went to look at your profile, which I remember reading a while back (I admire your spiritual overview and that pic near Moab is beautiful). I can tell you hyperbaric has really had a tremendously beneficial effect on the wired/tired/toxic feeling and on headaches. It sounds like you suffer from this and I think you are on the right track thinking it might help you.
