Orientation?

I have asked lots of questions about orientation already. So sorry for asking another.

Just wondering do they do any blood tests or anything at orientation? I just ask because if they do I usually get woozy if I don't eat a good breakfast first so I just want to be prepared. Or is the orientation just a information session.

It's just an info session. No blood work. No weigh in. Just sit and listen and follow along and maybe ask questions. 

No blood work just a lot of information. They give you a couple different packages to take home and one you have to fill out and sign if you wish to proceed with the process. :-)
