Nitpicky feedback: the layout needs a little tweakery for wide layout; as it stands 3 boxes on a wide screen is quite Large. A `max-width` on the categories and products (they look like the same CSS?) works well.
I especially appreciate the portable desk whiteboard; it seems perfect when I inevitably figure out how to not have an omnidesk (food and work included, which is an utter cardinal sin I know…)
I don't use Amazon so apologise in advance that these might not have affiliate, but I might also recommend the Ikea NILSERIK as a cheaper alternative for an ergonomic stool. A blue light alarm is absolutely useful: the Lumie Zest seems to have been discontinued (good! it was SUPER expensive) but I can't comment on if the newer ones have more gimmick faff. Either way the slow 30minute 'sunrise' is pretty good so I would absolutely recommend it.
If nothing else I can wholeheartedly recommend the youtube channel (and now book!) How To ADHD; Jessica's vids are real thorough, engaging, useful and with brains in mind! It might be super useful to sprinkle them into various articles, though be aware there are a WHOOOLE bunch of vids lol...
Anyhow a fellow ADHD haver you have my thanks and kudos for concept and follow-through! Keep going; you have my bookmark :>
