Somebody posted the table on the anhedonia discord. Yeah the current treatments for anhedonia leave much to be improved. Though I think nickname Jaiho (from longecity and the discord) recommended some polydrug treament for anhedonia. Can't remember which they were but he said it was recommended by a doctor who has gotten people into remission from anhedonia.
On the discord some have resorted to Parnate, Pramipexole, TMS and ECT treatments.
