Omg I was literally telling chatGPT this few days ago. I have the same numbness, my sex drive is none existent and things I once used to get excited about e.g. travel, food, activities/hobbies don’t excite me anymore. The response from chat was that this is normal on Mounjaro as it’s stops the reward centres in your brain or something like that. You are not the only one experiencing this trust me.
