Lately, the last few days, I have been getting tired at work....to the pint where I feel like I could fall asleep at my desk. I come home and I'm ready for bed by 8pm. I cant even watch tv laying down after dinner because i immediately fall asleep. I also fall asleep as soon as my head hits the pillow. It's insane.

I get about 8-9 hrs a sleep per night, work full time, and have a dog. I don't exercise daily, but I do walk the dog.

Any suggestion as to why I'm so sleepy all the time?

I'm not currently suffering from depression and haven't changed any meds in about a year. Maybe some job stress, but idk what else it could be.
