Eventually, probably yes. But as Martin says, you truly “don’t ever sleep”. The type of genetic condition you are talking about is very, very, VERY rare. It is called Fatal Familial Insomnia and only about 40 families worldwide have the gene that can cause this. And just because your family may have the gene, you still only have about a 50-50 chance of getting the condition. There are other pryon illnesses that can cause a person to never sleep such as picking up a human form of mad cow disease, also very, very rare. There also was an outbreak in England, back in the 1980’s I believe, of children who were given Human Growth Hormone from human donors who had the illness but once they figured out what was happening, only synthetic, lab produced Human Growth Hormone has been used. Therefore, that path has died out. Lastly, there was an outbreak of that type of disease from neurological instruments that were used in surgery on people who had illnesses of that type but once that was figured out, better sterilization methods were used and that path was also closed.
I know all about this because when I first started getting insomnia, I was convinced I might have this problem although nobody in my family ever had it. Also because right after I had a neuro procedure done, I started having my bouts with insomnia. When we first get insomnia, many of us start researching what possible medical condition we can have. I finally just realized after reading boards like these that I am far from alone and I most likely just had regular insomnia like a lot of other people on here. And when I say “regular”, I don’t mean to trivialize it as we are all suffering from something that has curtailed our lives.
