I haven't read through the whole thread, but I did once engage in aggressive rest therapy.
I was much better then than I am now, and I was doing 45 minutes of absolute rest followed by 15 minutes of activity. It was insanely boring but I kept at it. After about two weeks I started to feel really awful. i got all sorts of new symptoms. Then after a few months, my condition started to change remarkably and I improved rapidly. I knew beforehand that I was about to improve because I was constantly hungry.
Unfortunately I ultimately got ahead of myself and did too much, and drove myself into a horrendous two year crash that I am only just coming out of with the help of LDN. I tried aggressive rest during that time, but I was so sick that I could not physically rest enough as I still had to do things like brush my teeth and answer the call of nature. I am pleased you have reminded me about aggressive rest because I am now well enough to 'get behind' the ME as it were.
It is going to take a lot of willpower to do it again. It is really difficult. I think I may try to give it a go though. Want me to keep you updated?
