In the previous post, I defined CIDP and gave its typical known causes. In my case, the doctors told me there was no known cause. Personally, I think fatigue caused it. For the past two years, I worked a high-pressure information technology job that required me to work many weekends and late nights. In addition, I am a poor sleeper and often went days without a good night’s sleep. If you are familiar with CIDP and GBS, I would be interested to hear your comments.
