I found the following article which describes my sleep issues to a tee, except for generalizations they make about intelligence:
Sleep problems in autism, explained
The article mentions there could be a connection to Gene mutations being the root cause behind these issues. I do not know which genes are involved, but I have some problem genes, specifically homozygous C677T MTHFR, MTR, and MTRR genes which in this combination I am told are unusual. I have discussed with doctors, and have not found even one doctor in my area who is knowledgeable of these genes.
The other thing is that I have never been officially diagnosed with Asperger's/High Functioning Autism, but I have a friend who is trained in special education who works with children with autism, and she believes I have just learned to deal with issues and have overcome the social issues associated with autism. However, there are serious health consequences of living with these sleep issues.
