I tried this last night and even though it sort of worked, I found myself waking up a couple of times starting from around 5am and not getting back to sleep as deeply because in the back of my mind I was worrying that I'd oversleep and be late. In my sleepiness I forgot that I still set a "just in case" alarm, just for 8am. As a result I'm more tired this morning since I didn't get as good as sleep. I might try it for a few more nights, maybe the restlessness will go away.
