Don't add the GUARDYOUREYES website to your FAVORITES list. Each time I type in the words ...G-U-A-R-D-Y-O-U-R-E-Y-E-S... it's a real reminder! (Sometimes subconsciously).
What has helped me immensely is making guardyoureyes.org my homepage on my iphone browser, so that it is an instant reminder of my #1 priority (recovery), and it reminds me to step back and think about what I am thinking about and what I need to think about.
P.S. For filter options for iPhones and other mobile devices, see this page.
