    The way caffeine works is that it blocks the receptors in the brain for adenosine, which is responsible for slowing down the neurons in your brain, making you feel sleepy. It also causes the release of adrenaline, which is a stimulant and thus can help ADHD brains focus. Additionally, it makes your blood vessels (especially in your brain) constrict, which can make other stimulants take effect faster. As if that weren’t enough, it also slows dopamine reabsorption, which feels rewarding (the major contributor to caffeine addiction).

    These are the upsides, but caffeine comes with serious downsides if you use it regularly (i.e. more than twice a week). In particular, it seriously inhibits your ability to get truly deep, restorative sleep, even if you only have it in the morning.

    Tl;dr: It can make you feel more awake, but it can’t replenish your energy stores. It basically puts a pin below the needle of your mental fuel gauge so it can’t drop below half a tank, but doesn’t actually fill the tank.

  • Except in very rare configurations (i.e. not 99.9% of residential), you do not want to have multiple paths to ground within a system. All grounds should go to the tied ground/neutral bus in the main breaker panel, which then goes to earth via a ground rod or a clamp to a copper gas/water line, etc. Otherwise you can have current flowing in ways that the system isn’t designed for, which at the least can trip breakers and GFCIs, and at worst exceed the rating of the wires in a short condition and cause a fire.

  • At least for me, I have ADHD—if it’s out of sight (i.e. another bookmark in one of the hundreds of folders I have), it ceases to exist, no matter how important or interesting it is.

    I have 6 virtual desktops for current projects, with all of the tabs (and other applications) for each project on a desktop, and with a Firefox window for each “topic” within that project. I go through and close out old windows periodically (i.e. when I need to free up desktops), saving anything I might want to refer back to with the Tab Stash plugin. Importantly, I also have the Auto-Discard Tabs plugin so they aren’t using RAM until I need them again.

    It might seem messy, but it’s what works best for my brain. I do at least try to not have more than 12 tabs per window. On rare occasions I’m even successful! 🙃
