Do you guys feel emotionally flat on lithium?

I've been taking lithium for a while, around 350 mg, but I feel like my emotional reactions to things in life have become more muted. All my friends are saying that I don't go out with them anymore, but from my perspective, I'm in an amazing phase—good job, good salary—and to me, I'm still seeing my friends as often as I always did But if friends from different groups are all saying the same thing, maybe there really is something off. Have you ever felt like that too?
