I can only share with you what works for me.
First of all, i hate to break the news to you, that as far as I am aware there is no magic word that will make this problem disappear. Until not long ago, I also looked for the solution to get rid of my problem or to help me "overcome" it. I learnt the hard way, that for me lust is something much more powerful than me AND THAT IT IS HERE TO STAY. Accepting this was very difficult, and is something which I have to remind myself of constantly - because it means that I am what the White Book calls a "love cripple" - that I react to lust differently to normal people. Now, THAT was a hard one to swallow!
But I subsequently learnt (slowly, not al regel achas, or with one word!) that there is another option; that however convinced I am that if i do not act on my cravings I will go crazy, I learnt that by admitting to others that I am powerless and by genuinely reaching out for help, ultimately to HaShem, that I CAN survive without acting out, and that I can even remain sane.
May HaShem grant us a sober and sane day.
