What they say about fasting....

I read some where that if you are fasting one of the things you should do is read about fasting. So I decided to go about doing the same thing here for dieting and such. I've noticed that I've been doing really well without cheese in my life. I wonder what I'm missing and what I can do to replace the vitamins that you receive from cheese. How can I cut out the cravings? What am I really craving instead. I want to find out more about carbs as well. I'm really in to rawism and it definitly excludes both things. I want to really get into what I need to get started and how I can get past certain cravings.
