A mind is a terrible thing to waste

I feel like I ramble and/or repeat myself a lot. Have I run out of words, or did I run out of thoughts to fill the words I am forced to constantly say? Right now I'd like to try going an entire day without speaking. It was terrible when I lost my voice a few months ago and could not speak for three days, but all I'm asking for is the option of speaking when I actually want to. A good majority of what I say these days is meaningless dribble I've been taught to say like a trained monkey, and as a result, my mind has turned into mush. When do I get to exercise my brain again?
