Does listening to audio books help? That way you could listen and do something else at the same time? Then you wouldn't be so focused on one thing and would require less need to talk about it immediately? Just a thought. If it's an audio book, you could also technically talk aloud (maybe?.) I find that Te really needs/wants to vocalize things learned. I think that's often why I am probably seen as the crazy person that talks to herself while driving...well okay, people probably just assume I'm on the phone, so it's all good.
Another thing that helps me, is writing notes on the margins of books. I know some say it is sacrilegous or something, but it helps process the things I am thinking at the time while reading. I haven't quite found a way to do this with e-books, though. Another idea, have you thought about creating a blog? Then, you could throw out your thoughts to your heart's content...
