This has been one of the most disapointing times of my life. I would rather work than be sick. I just hate it, but have finally accepted the fact I have no control over it. I also have polymigratory arthritis, diabetes, history of pneumonia times 2, asthma, etc. Good luck to you.
Some people can tolerate working full time, part time or on a temporary basis.
Yes I have FMS, and have had it for probably 15 years, although not diagnosed until last year. Although they will tell you it was from decreased performance issues. And yes, I had to take off from work several times. My boss would get mad at me because I'd get really sick at work on occasions and have to go home. She also wanted me to be on call when I was so sick I couldn't be at work in the first place.
