Pramipexole is not a stimulant and I think is worth looking into
-Pramipexole (Mirapex) for anhedonia and negative symptoms?
In my case, I originally thought I had poverty of speech but eventually realized that I had nothing to say because nothing interests me and I do not derive pleasure from talking… If you observe people discussing, you’ll notice that the reason behind why they say something is to derive pleasure from it (like making others laugh and intrigued by telling a funny anecdote for example), or to share an interest with someone and thereby to “bond” …the reason behind most of casual conversation stems from motivation to have a rewarding experience from the discussion…
Basically my poverty of speech is rooted in the anhedonia itself…it’s not a separate symptom
