yes i read in stephen laberge's book that one should do a reality check every hour to get your mind into the habit of doing one while sleeping as well. Also if you wear a watch ,put it on the one hour chime, do your R.C. during the day, and while your sleeping your subconscience will hear it (i dont hear it so hopefully my subconscience does) and it may help do an automatic R.C. during sleep
