My solution: a 3-hour focus mode browser extension.
1. Install the BlockSite chrome extension [1]. 2. In BlockSite settings, add HN, Twitter, and any other distracting sites to the Focus Mode list and set Focus Mode time to 3 hours. 3. Ensure you uninstall all social media apps from your phone 4. When I find myself opening a new tab and typing "n" to get a dopamine hit, I then turn on my 3-hour focus mode.
