Since that one person said that the proper way to do reality checks is not by a cue to do it, just every once in a while by memory, I have stopped doing it by the beep of my watch. Also, as one person put it "don't moan about not having lucid dreams if you don't keep a journal". I started a journal today and I'm starting to not use my watches beep to make me do reality checks...
Just felt like sharing...
