I have been just informed that I have narcolepsy, I have been reading online that the flu shot has caused narcolepsy in children. Back in 1980s I was in the services and had to have a flu shot. Could this have caused me to develop narcolepsy? I have never had a flu shot til I was in the service. The doctor told me that I have had this for several years and that it has begun to get worse. I will be 50 in May.
