Any bad experiences with raw food?

Hi, I'm new to the forum, and and thinking about going raw in the new year. I'm am inspired from reading a book by Shazzie 'Detox your World' - you may have read it, and feel I am ready to give it a go.

How long does it take from eating raw food for people to get over the bad effects of the detox that many people experience? The reason why I ask is because I am getting married in July 2005 and I do not want to be ill for that.

Is there any advice that you can give me to ease my transitioning into eating raw food? Also is it perfectly safe to eat a raw food diet when pregnant - the reason why I ask is because I hope to try for a baby after I am married.

Many thanks
