Better suggestion: block these sites entirely. Reddit and YouTube are wastes of time if you are just 'checking in'.
Use YouTube-DL to download videos from specific creators and watch independently. I haven't figured out how to view the actually useful subreddits without having access to the frontpage feeds.
Feeds are one of the worst things to be invented in the Internet age. I can't imagine how far behind we are because they've caught otherwise smart people in this insane dopamine trap.
I keep Instagram to keep in touch with friends abroad.
I keep Facebook because certain communities and events only happen there.
For some of us, it is plain better to only block short form video.
