NONFICTION ISSUES

I have a problem. I've done quite a few nonfiction books by now and I have a confession to make. I don't always remember all the facts about them... especially the ones done a few years ago. I'm doing a local radio show tomorrow and a panel in a few weeks. I feel like I'm cramming for an exam! I become all Miss Expert when I'm working on something and then all the dates and facts go out of my brain just like when I was in history class way back when. I don't know if this is normal or not. Anyone out there have this problem? Should this stuff be sticking?
