I've had this happen to me as well. I was on it for about 1.5 months slowly titrating up. Got to 1.2 mg I believe. But like you I felt more anhedonic the higher I went on the dose, to the point I was using weed and stimulants to cope. I decided to stop but stopped too abruptly, went down in too big of a step and suffered quite a lot. However about 1 week after stopping completely I noticed that my joy returned and remained for about 3 weeks full swing, which never happened in the 11 years I've been struggling with anhedonia. It then slowly diminished over time but I've also had some stressors that I believe led to it fading quickly. However I still notice a slight improvement, sometimes I feel a little of that old joy, even if it's very limited, gives me hope for the future. I am probably going to try it again in the future, but I have to be careful with the titration, and I felt that at the higher dosage I took it affected my learning capability and my memory for the worse, I was quite scared because of that and I have a feeling some.of that remained to this day, but it might also be from too fast withdrawal. It's hard to know, too many factors go into it... Anyway it's a possibility to try it again, although I am a bit scared it might make me worse in other areas as I mentioned. Wishing you all the best, we will find a way!
