I experienced a similar anhedonia when quitting caffeine. I don't think the caffeine itself was the problem, I think it was just helping a lot more than I knew with the inertia of circling the pit without tottering in.
Turns out I needed stimulants from time to time, just not that one.
What stimulants have you landed on? And do you feel they're better for you?
I'm pondering getting a coffee machine at home. 400 EUR is not a sizable investment and one I'd have forgotten about it 3 months but I'm getting cold feet when it gets to committing.
Americano coffee definitely picks me up and is a full net positive for me. But that's only if I drink 2-3 times a week. Not sure how it's going to be if I start getting it every day.
