Actually, though a coworker did get sick with me the first time I got ill, but I got better for a short time - he did not. He had to quit his job and go on disability. He was never diagnosed to my knowledge. Then I got ill again and was so knackered I had to quit my job, but then moved and was a little better for about 4 years, then got sick again with the fatigue and haven't got my legs under me again. West Nile did break out that year we got sick and I'm pretty sure I had it, but not sure if my coworker Larry had it. Larry and I both worked on computers and the web site, I thought maybe our brains just broke from too much computer use. He was a few years older than me and a smoker - I figured maybe he drew the short straw because of that and I would have been in the same boat if I had been in his shoes. I was in my early 30's back then.
I have been sickly my entire life though and have never had robust health. This fatigue though - man it's a different animal. I get worn out doing dumb stuff like having to watch a movie, god I hate watching movies now, it's so much work. *sigh*
