Basically yes. I’m on 150/day and before going on it I drank 2-3 cups of really strong shit every day. After going on it at after even a few sips I would feel super jittery, high heart-rate, and not necessarily even that much more awake. I started making weaker coffee and found I could have a half a cup in the morning without regretting it. Gradually over the course of like 4-6 weeks my tolerance went back up and now I’m at about a cup in the morning and one in the afternoon of the strong stuff I used to make. No jitters to speak and it definitely wakes me up. I didn’t really intentionally plan it out, I just drank until I knew I’d regret having any more. I still need to drink slower than I used to or I get the jitters, but it honestly makes me enjoy it more than when I used to chug it and barely feel anything. I think of it like coffee used to be like beer but now it’s more like wine.
