RCs dont always work that well for everybody. Regular RCs dont work at all for me. The best kind of "RC" is simple general awareness. Your environment can easily tell you if you are dreaming. Doing an "RC" could be to ask you who you are, what you are doing right now and why exactly, where you are..what dayit is..does that make sense, is your environment making sense with what you have been doing in the near past? Stuff like that. That might seem like a lot but you can put it as 'general awareness' which is more of a feeling then literally going about asking all those questions. it takes abit more practice but its effective. to me it is at least ^_^
