Interrupt your habits.

• Uninstall the app, if you use that.
• Log out in your browser.
• If you use ublockorigin, add reddit.com to the custom block list
• Use a password manager, change your password to something you can’t remember. Then in your password manager, put a prefix on it like (take-a-break), so you have to go through the hassle of editing it to log in.

You don’t need to be up to the minute or even the day for most of your interests, you can catch up when you have time to do so intentionally.

Interruptions cause you to slow down and give your will power a moment to catch up and intervene.
