The trouble with Urge Surfing for browsing is my urges to browse are so quickly acted upon that there is never actually a feeling of urge to tip me off. It takes milliseconds for me to spin up a new tab and get onto reddit, and the vast majority of time that means I'm already subconsciously browsing and I won't notice.

For me it took banning the sites entirely, so that when I am met with the "could not connect" screen I realise what's happened and I need to go be mindful so that I can get into an intentional mindset again.
