I am writing for a friend of mine who also has CFS, but who is much sicker than I am. He had a bad relapse this spring. He has very bad days and some OK days. His question is this: How does one get out of the cycle of the good and bad days after a relapse. How much should he do on bad days and how much on good days. One of his main problems along with the fatigue is the dizziness which stops him from driving a car even for a few minutes to go to the grocery store. He is pretty much stuck at home all the time. How long does one recover from a bad relapse?
