Now that I'm not working I only use the sunset simulator which dims the light gradually over a time I set so that I fall asleep and sleep in the dark instead of just passing out at some point.

This sounds interesting, as I fall asleep to early on the couch, and then wake up in the middle of the night. It takes me hours to get back to sleep, and I'm exhausted in the morning. Anyway, if you could provide the make and model of your simulator, I would appreciate it.

Thanks.
