Anyone with Delayed Sleep Phase have a Pineal cyst?

Hi. I'm new to the group and was reading about other folks with Delayed Sleep Phase disorder. I have had this issue for about 35 years, and although I have been on sleep meds, I was not officially diagnosed till last year. I was diagnosed back in the 1980s with a Pineal Cyst, and for YEARS asked all my sleep providers if it could be related to my sleep issues (the pineal gland is where melatonin is produced). I am finally seeing a sleep psychologist who is assisting me in addressing it. I'm not too hopeful after reading everyone's posts. Wondering if anyone with Delayed sleep phase also happens to have a Pineal cyst or if anyone has any info about the relationship between the two which could affect treatment.
