Does it Really Work?

I am looking at some clinicallix online this morning and reading all about it. I'm trying to figure out if it really does work. I have seen some people who tell me they have tried it and wasn't too pleased with it, but these are also the type of people who doesn't actually go by directions. I have this one friend who really loves it, and she is the type that uses something exactly by directions, so I would love to get more input about this problem. It never hurts to get more opinions when your trying to make and important decision, right?
