what are negative experiences or negative effects you've had from getting the epidural?

So my goal is to go natural and I'm trying to get committed as I possibly can to it because it's important to me. The more I read about going natural the more I want to do it. However I still have curiousity about what people experience with taking the epidural. I want to hear bad experiences mostly to push me to really commit to going natural. I know that sounds bad and I apologize if that offends anyone. I just really need some more motivation and I find the stories interesting and informative.
