I had a second round of RTX at the end of Dec and one on the 1st week of Jan. Again I had an excellent response to it. Took about 3 weeks to feel better. I may have felt better sooner but I had an infection in my picc line. I have realized the RTX seems to make all my autonomic complaints much much better. Second to that is improvements in my brain fog and 3rd the profound fatigue is improved. I am now off my feeding tube, which I credit to RTX, I have no appetite at all and have major motility issues when the RTX wears off .. Now I can take in a mostly liquid diet and I seem to be holding my own. My ability to sweat and have a blood pressure are better and all neuropathy in hands and feet has dramatically improved. As I said all autonomic problems have greatly improved and when the RTX wears off the problems come back. Hope this info helps someone somewhere !
