I'm almost exactly 1 year coffee-free (not caffeine free, but significantly less because tea is much less addictive for me).

Also positive in the long-term for me. Fewer digestive issues, less spiky dopamine sensitive or impulsiveness and performance during the day, better memory. I wish it weren't so.

But damn was the 3-6 months of anhedonia awful. I still feel pangs of it.
