Heres a thought, Do an Rc everytime you realize you need to do something This is my new technique, since I too wake up more than a couple times right before my alarm goes off. Doing both sounds like a good idea though. I'll try it out.
I've recently noticed that I realize I'm dreaming almost everyday. I'll wake up for school and accidently fall back asleep, dream, and in the middle of the dream I'll just spontaniously remember I have to wake up and get ready. I never seem to take advantage of this sudden realization. I've actually been meaning to test this technique out.
