Hello there. My CFS started recently on exactly 29th of October. After a sudden vertigo attack it all began. In the beginning it was very though: severe insomnia, POTS, huge brainfog, bouts of fatigue (mostly late morning-afternoon hours) and problems to walk more than ~1km per day. Now, some months later, in which I mainly rested (was in a hospital for 6 weeks to treat my insomnia) I feel I am in remission, because my only problem now is a little bit of brainfog (10% of what it used to be). Still, I am pretty sure that I really have CFS and not something else, because it started suddenly after a period of severe stress and I fulfilled most of the Canadian Criteria: 4/6, everything else than pain and 6 months duration. Also, my sister and my uncle have CFS, so it seems to run in my family. I'm back to work for a few weeks now. MY colleagues are very kind and understanding, though they think it was depression or something alike. What should I do to make sure that my improvement lasts? Edit: I don't dare to do sports, so I can't tell about that and my lymph nodes are stil swelling every day.
