I, too, have sever fatigue. I am a 3.5 year pancreatic cancer survivor and am currently NED. They doctors relate my tiredness to low iron, which is a result of mal-absorbtion of nutrients. No matter the amount of sleep I get, I could always use more. Like you, I get up every day and put one foot in front of the other. Really don't have a choice. Agree that fatigue is a huge problem with cancer patients.
