Good luck, and thanks for everything you’ve shared, some very thought-provoking stuff - like TWF said, please don’t be a stranger if you ever feel like doing a big old dump of gnosis and ponderings.
I use Leechblock to limit time I spend on certain sites (it’s a Firefox add-on that works brilliantly) and you can use it to completely ban yourself from a site, setting a window where you can only turn that option off between say 5am and 6am or a similar time one day a week, so that any renewed access requires a particular planned effort to restore.
You can also use it to lock yourself out of a site after a set amount of minutes or hours, on certain or all days of the week, and even set it to redirect you to a webpage or stored photo that reminds you of your goals - just mentioning this because I too am easily distracted, and this does the planning and willpower for me!
