Yeah the title is kinda meh. Teenagers on the robotics team I mentor have figured out PID loops and calibrating them (and how funny robots are when you don’t)

I was on one of those robotics teams, and I recall this document being passed around as suggested reading on that team. It’s probably worth considering that this was written in 2000, when it was a more niche topic, and was probably itself a part of what made PID programming more accessible in the first place.

I tried this! I went completely caffeine free for over a year and was... fine? But way more tired all the time, and generally having trouble focusing on tasks. In my particular case, I suspect caffeine is a self administered coping mechanism for mild ADHD tendencies, and without that I became much more sensitive to the food I was eating and my changing energy levels throughout the day.

Eventually I realized I had stopped coping with caffeine and, instead, started coping with *sugar*, and gained 20 lbs in the process.

I'm back on caffeine again, but the rules are: one (1) cup in the morning, however I like it. Then water for every other beverage all day long. That seems to have done the trick, and now I again sleep through the night and can more easily remain focused throughout the day.

The point is, experiment, yes! But it's your body and your mind. Take notes and figure out what works best in your case. Everyone is a little different.

I second the “experimenting” thing. I would recommend going caffeine free for a couple weeks every once in a while, just to kind of… keep track of the addiction. I’ll quit coffee occasionally, historically usually for a tolerance break if it’s getting a bit too much, or to just kind of “reset” my brain chemistry.

I ultimately found that reducing was a good idea, but I personally like coffee a lot and feel it adds something for me. I also have adhd though, so I’m probably playing with a slightly different deck on the “how stimulants interact with the brain” front.

I have found that having controls and limits around caffeine intake is a pretty good practice. I found that to reliably sleep well, I need to never drink caffeine after noon. And reducing my intake a bit helps as well. But from there, I haven’t seen much further benefit from quitting entirely.
