Well one method that was suggested earlier (forgot who it was, sorry) is that throughout the day you focus on yourself and where you are etc. Once you get used to this, you will always remain focused and not let your thoughts drift to much. This will make it harder for you subconsious to trick you.

Again, like everyone says, its only been 4 days. Just be patient and give it more time. It's understandable that you are excited about this.
