Yes, I have to watch night, because I'm tired of working all day and worrying thoughts start to take over my brain. If I let them I will get very depressed at bedtime. I think when the busy day is done, our brains go into overdrive with ruminating thoughts that lead us into depression. I find it helps if I listen to relaxation tapes at bedtime to get my brain to slow down. That's just me. I'm sure others have different experiences. Best wishes.
