How talkative is your inner monologue?

I found out yesterday that not everyone has an inner monologue which really blew my mind. For me its like my inner monologue won't stop talking. I guess my thoughts are directly expressed through this monologue and I am thinking pretty much all day unless I am focused on something. So I was wondering what other people's experiences are and if you even have an inner monologue. Also another thing I was thinking about is how vivid my inner voice is yet I would say my visualization ability is subpar. So I wonder if people who are better at mentally visualizing something have a less talkative inner monologue i.e. they think more with visuals rather than words. Thanks!
