I've had so many Lucids ruined from my alarm clock going off in the morning!
I'd never use an alarm if I didn't need it to get up for work.

But then, I always wake up naturally often during the night. If you are thinking about wake back to bed, I usually just do short ones when I need to get up to use the bathroom. Ten fifteen minutes at most. A lot of times I just do five minutes now because of it being too hard to get back to sleep sometimes.
