Like EAUO said, write 'em down and put 'em in a drawer (whether figuratively or literally). You can also discuss them with other people, who might get ideas from them and/or want to 'burrow' the concept, so to speak.
As to your other question... well, I've never felt like this. In fact, my problem is the opposite; a dearth of ideas and frequent bouts of writer's block.
