I’ve done it a few times over the past year and noticed that really the only thing that changes is that I stop getting headaches on days I don’t drink coffee. I don’t generally use coffee to “wake up,” in face I really only have it in the morning if it’s a _really_ early day for me or if I’m at a hotel where it’s served free or something. Most of my consumption is around 4pm, and I find that it helps me zero in on tasks better and just grind some code out. It doesn’t make me jittery or anything, not unless I have an empty stomach. I might be an outlier, but I generally find it’s a net positive.
