Yes, all sounds familiar. You have a good schedule going, so keep up with it.
Meanwhile, one thing I learned by trial and error was that if I have eaten anything inflammatory to my system, my sleep is terribly broken... I wake up, I ache, I can't go back to sleep, I have to visit the bathroom two or three times, etc etc.
But, when I have managed to get through a couple of days irritant free, I sleep like a baby. It really is amazing.
Thing is, everybody is different as to what foods aggravate their systems. In my case, the worst offenders are: peanuts, eggs, almonds, oats, cranberries, sunflower seeds, agar agar, vanilla, flax seeds, milk, spelt, chick peas, flat fish, pineapple, bananas, pear, mandarine, brussels sprouts, oyster, herring, mussels, barley, spelt, buckwheat, wheat, gluten, cheeses, mustard.
Anyway, I've noticed from the food sensitivities tests of others that the worst offenders are eggs, nuts, dairy (milk and cheeses), wheat and related. Rice works for me, and most meats, and a few veggies. If I stick to that, mainly, I'm fine. And when the inflammation is down, I sleep very well and all aches and pains go away.
I don't think HBOT is gonna cure that sort of thing if it is present.
