My Mom just mentioned that she doesn't think you can take make-up with you on the plane anymore...is this true

What's a girl to do?
I'm going to NC for a week (driving to Syracuse, NY to board so we're flying domestic, not international)...is it true that I can't take make-up?! I can't afford to go buy all new make-up when I get down there & just leave it there (since I won't be able to bring it home, either).
Does anyone know what else I can't take?
I know you can't take bagged lunches anymore (we always used to do this - sandwiches and stuff), but can you take packaged food? Or if I buy a packaged snack at the airport can I take that with me?
I haven't flown since 9/11 and we're flying on the 14th. I'm getting stressed.
