Realize that you can achieve it. There is nothing different about you and the only person who can make you PMO is you
There is absolutely nothing to give up. On the contrary, there are enormous positive gains to be made.
There is no such thing as a peek or visit. PMOing is a drug addiction and a chain reaction. By moaning about the odd PMO you will only be punishing yourself needlessly.
It will not go away because you bury your head in the sand. Remember: like all crippling diseases, it not only lasts for life but gets worse and worse. The easiest time to cure it is now.
All PMOers, if given the opportunity to go back to the time before they became hooked, would jump at that opportunity. You have that opportunity today! Don't even think about it as 'giving up' PMOing.
You fear failure itself. Do not worry.
You do not need porn or PMO. It is not food; it is poison. When the pangs come remind yourself that it is PMOers who suffer withdrawal pangs, not non-PMOers.
You are hiding from nothing. The worst thing that can happen is that you fail, in which case you are no worse off than you are now.
Don't worry about it. Just think: what awful thing could happen to you if you never again PMOed? Absolutely none.
Remember you did not enjoy being a PMOer. That's why you stopped. You do enjoy being a non-PMOer.
