Messing up for one day isn't going to ruin your chances forever. Just try to get in the habit of remembering to do it. It might help to have some kind of alarm that goes off every hour or so to remind you to do RCs. If you have an iPhone/iPod Touch, there's a specific app for it called Lucidity. Also, as others have said, make sure you are trying other methods in combination with doing RCs. Hope that helps!
