22.5mg seems to be the medium to large dose for first time users. As I said, that one ended up making me feel really sick when I was coming down.

You also have to be careful with taking the pills, taking more than a few can damage your liver due to the acetaminophen that they add in. You can extract the vicodin by using a cold water extraction technique, though.

I have the liquid stuff, and there's no acetaminophen in it, so I'm all good there.
