I have not gone the whole way through the course yet myself, but I'm guessing that you don't have to really start over.
The core I think is the Feeling Exercise - use that morning and night. Try the Inquiry process on a couple of things that may be bugging you to re-acquaint yourself with that too. Once you're back remembering what those two things are all about again, do CD2 (or CD3) which is the paraliminal that program yourselfs to automatically use those two.
If you have the Deluxe version of the course, and you haven't listened to Bobbie Stevens' interview yet, get that into your cd player right away and play it. It, itself, convinced me I have to get her book, even though her 7-step system is already integrated into the course. Her story of how she simply decided that she will buy herself two townhouses and a new car, and then she did special breathing, stretching and meditation exercises to rid herself of stress, which made it possible for her to listen to intuition which told her to be a real-estate agent, though this wasn't her background at all. She made, in the first year, the exact amount of money that allowed her to buy the two townhomes, furnish them, and also the nice car.
I'm sure you will get better advice.
Just remember to stay in the NOW, which means you stay out of the trance!
