I have had CFS for almost 4 years now, and do work FT yet with this. I have tried many combinations of things, but Adderall has been my savior in allowing me to continue working. I take it 5x week as to not build a tolerance, it has worked for me thus far 2 years now. I also take these supplements: Ace L Carnitine, creatine, Vit B12, and D Ribose. NT Factor is another one I cycle through for mitochondria repair. Melatonin for sleep, as that is so important. This combination allows me to work FT and have some social life, and to exercise a bit. Without this combination I am sure I would not be able to have this quality of life. I am 51 years old, and will probably have to retire early, but 55 may be within reach. It really makes you look at things differently, and you have to be able to tolerate a certain level of fatigue 24/7.
