Dane,
The first step in 12 step addiction recovery programs is to admit that you have an addiction. It can't be treated like it is your wife's problem, you must recognize it for what it is, your problem. Personally, for me as a recovering PA I know that I must treat P like a plague or even a sin. If I tell myself that I don't see anything wrong with pornography then I will eventually embrace it again.
I'm not a married man so take this advice with a grain of salt, but I believe that the most important part of a relationship and a marriage is open and honest communication, not sex. By keeping secrets from your wife you are not being emotionally intimate with her and eventually this will hurt your physical intimacy.
I wish you the best of luck and I am glad that you have taken the first step by acknowledging your desire to change. We are all here to help each other. Good Luck.
p.s. I also have RLS (Restless Leg Syndrome) and have found that if I take an Iron supplement once in a while it helps a lot. After a month or so it starts acting up again so I take another Iron supplement. Remember to be careful since Iron is a heavy metal and you do not want to take too much into your body. see
