I have an active inner voice. Never stops yapping but I like it.
For two weeks of my life, I was on Wellbutrin. [ended up having a full body bad reaction to it after 2 weeks – it was a generic so it probably had oddities in it).
While on Wellbutrin, there was absolute inner silence. I don’t remember much of that period of time because there is images but no dialog in my memory. The world was more interesting than my thoughts, which I remember couldn’t fully form; I’d get a half a sentence and it would be gone.
