many of us with fibro never get sick...by that I mean the normal stuff like colds, flu, upper resp infections, etc. So last week I went on a diet and ate nothing except protein and fruit for 3 days. I was trying to lose 10 lbs quickly. I only lost 4 lbs but I did feel a lot better overall and I also started with a cold. Stuffy head, scratchy throat, etc. I was wondering if because I was getting 'better' by eating so good, my immune system slowed down a bit and allowed me to get a normal cold, like normal people do. Any thoughts on this? I'm stilling fighting it off and it hasn't really turned into a full blown cold or anything. I'm back to my normal food intake and I'm anxious to see what happens.
