Have you considered learning to deal with temptations? As you have read in my reply to your post in my thread I don't use porn blockers mainly for that reason. I think that to really deal with our problems we should come to the point where we are able to look a temptation right in the face and say "No, this is not I want" and move on. If you are not comfortable with giving up your blocker (which I assume you are not), perhaps their are other temptations you can train this with. Kelly McGonical mentions some interesting excersises for that in The Willpower Instinct.
