Hey everyone,

My sleep schedule has been getting really bad lately. These days, I don't seem to feel sleepy until after 11 AM. Just yesterday, I ended up falling asleep at around 12:30 PM.

My employer was kind enough to accommodate me by allowing me to start work a little later, after lunch. That arrangement worked reasonably well for a few months, but lately, my sleep schedule has been shifting quite a lot, making things difficult again.

I'm struggling to understand why my sleep timing keeps moving later and later, even with the accommodation.

Has anyone else with DSPD experienced such significant shifts in their sleep schedule? Does your sleep timing remain relatively stable, or does it keep drifting over time?

I'd really appreciate hearing about your experiences and how you've managed this, especially while holding down a regular job.

Should I try light therapy? Will it work and slightly advance my sleep back to my usual sleep time of around 4 am? If yes, how long it takes?
