Act like everyday is the first day.

When you pat yourself in the head for the days you've managed to go through, what you're basically doing is sending a message to your mind that you're already accomplished, and when the urges come you get that "I've done enough, just this time won't hurt thought", and then you relapse.

Act like everyday is your first day, you just stopped that nasty habit -can you even go one day without masturbating?- It puts you in this mindset, and makes you way more self-aware. This is helping me go through now, and I hope it might help you.
