Has anyone permanently lost their internal monologue?

I’ve been toying with the idea of meditating to quiet my inner voice, because it’s been particularly noisy these last couple years and I’m starting to feel like I’m going crazy. But I’m worried about who I will become if I don’t have it, because I spend a lot of time in my own head and I don’t want to lose my ability to think about things in the way that I do right now. If anyone has had any experience with meditating to quiet the internal monologue, please let me know if you found it rewarding and whether you are able to control your internal monologue on command or you lost it entirely.
