re the peroxide, you can also do footbaths if a tub is not available to you.
all of your symptoms point to metal poisoning, probably mercury but you'd need hair test.
cutler even talks about people who have salicylate issues as being a mercury problem. your glutathione experience also points to mercury.
iv ozone is not the way to go, saunas are the way to do it for men. consider this in the future, but it sounds like you won't be getting into that any time soon. i've heard similar stories from people doing iv ozone, but never with saunas.
have you noticed any distinction between raw fats and cooked with your intolerances? it is something to consider.
look into stanley bass's sequential food combining to put on weight. i knew someone who had their gall bladder removed and wasted away to almost nothing and the bass thing worked really well for him.
you might notice a difference too with raw proteins like sushi, but then there is the mercury issue again. raw egg yolks are very good for the adrenal glands. if this doens't pan out then..
try cooking the snot out of all of your foods low and slow until it gets completely broken down, this might get around some of your issues. even do it with vegetables, beans, or whatever you can get down.
if the raw fats work out then add a bit to juices to help ground it and be less cleansing.
i wonder also if you have considered the doug graham program, which is 80 percent of calories from sweet fruits. some people with cfs have recovered with this program. fruits are very easy to digest and shouldnt upset your liver but it could also cause cleansing in other areas. the easy-in sugars should get your energy up if you are able to tolerate the program.
personally i did Liver Flushes when my adrenals were fried, but i wouldn't recommend this to anyone, and i have no idea how being on cortisone would affect this. you could be in a stage where your adrenals are shutting down due to reliance on the drugs, perhaps you need to up your dosage?
you said you tried licorice... it is important to get a good quality extract and not just the leaves or even roots. the one i took was like a black thick tar. there are others that work but i'm pretty sure it has to be the extract. the plain plant can cause blood Sugar imbalances and other types of havoc. licorice is also a cholagogue and will cause bile stimulation, so in that regard it can cause exisitng blockages to worsen. also long term use can raise blood pressure and imbalance potasssium levels. you could try other adaptogens like ashwaganda, rhodiola, siberian ginseng.
look into a good qaulity whey powder that is cold processed and hydrolyzed.
keep a journal too and don't get discouraged when things don't work, just move along to the next attempt.
