I'll add also that in my own experience, one of the biggest pitfalls is relapsing within the first few days. It's like you're trying to get out of the pull of falling into that hole...the first few days may be rife with self-doubt, second-guessing, and urges but once I'm out of the woods there, I'm no longer buffeted by memories of PMO. This is particularly prevalent in the first couple of days. One example is that last night I was drifting to sleep, and automatically got mental images of scenes from videos. After the first few days, the urges and association or imagery lose their intensity, but this is not a time when you can yet rest--the discipline must remain constant, just in a slower way--by doing things like modifying your environment to eliminate the option of PMO. Get K9 if you have windows or mac. Get a router or VPN that blocks adult content for the whole network. Have a routine set up for when urges hit so you don't even have to think of it. The point is to, in your normal and reasonable mental state, think two steps ahead of the 'porn-trance' state of mind. Speaking from my own experiences, one thing I have noticed is that after a certain amount of time away from it (between 5-10 days I'd say) I start to recognize things about myself and PMO habit that it's like were wholly hidden before. And I start to actually get fulfillment and joy from small experiences I previously viewed as somewhat flat and quotidian. It's like looking to the ocean floor when the water is calm and the sand has settled--until that point, I'd been caught up in the waves, unable to see clearly to the real person at the core of myself. There are plenty of reasons why to start, and you'll find more as you get further into it.
