You can do it. I'm an IT Specialist for a regional health care system including 4 hospitals. I have no formal education. If you start doing it, and like it, before you know it you'll be able to pass an A+ without even needing to study. After that, you can pick up a certification here or there as you get into something that needs it. That's pretty much the way that I learned, and in an IT dept of 30 people, I'm considered to be pretty damn good at what I do :).
