Yes and No(how Jewish of me to answer this way).  For someone "normal" than yes, your proposal will probably work.  For someone addicted like me, than no, yiras shamayim is not enough and isn't even a tool used in recovery. 
How can someone tell if they are addicted?  There is a test at sa.org that may provide an answer.  You may be able to search for that test here on the forum. 
Honesty.  How "impossible" is it to stay clean?  Is it only difficult, or does it feel like a choice between death and falling?
If you think it will honestly work for you than what do you have to lose?

even for addiction if my wife would be seeing how i do it will stop me! so knowing and believing that the eibishter sees doesn't stop me! is it a lack of אמונה ח"ו?? i don't know i'm all mixed up. but can it be that all i learned in all the musser sforim אין דבר העומד לפני הרצון is not true?

i was roaming around GYE today and i noticed one of the screen names "silent battle"  and it got me thinking. We all fall because the yetser hara convinces us that we are alone and we think no one, not even Hashem, knows what we are about to do. (as a side point, if we were to really live with the constant reality that hashem is with us, we wouldnt sin. Imagine being in the presence of a gadol hador with his full undivided attention all on you, would you even be thinking of sin?? something to think about). I couldnt have thought of a better name myself, it is a "silent battle" that each and everyone of us go through daily, with no one to talk to who can understand and really help. not to mention the embarrassment that one has to go through in telling your Rav whom respected you as a talmid and ben torah, that you have an uncontrollable, taivah related addiction. But here is where it all changes, we no longer have to suffer in silence, we no longer fight alone, together we form a battalion, a legion of soldiers that are fighting as one, all for one and one for all.
We are soldiers fighting a "milchemes hashem" and when soldiers come home from a battlefield triumphant and jubilant, they are made into heroes by there fellow comrades, this gives them the strength to stand another day. 
With all my brethren on GYE I know that i have an army of fighters behind me everyday, that will share my pain and help me heal, strengthening me to fight till the end. I dont know how i ever thought i stood a chance by myself.
Please do not underestimate the power each of us have to help others and ourselves. You can help change a life, or save a marriage by a simple word of encouragement. You are a vital piece in a jigsaw puzzle that can paint an awesome picture when put together with all the other pieces,  a picture that expresses the power of am yisrael - k' ish echad b'lev echad (a nation that is like one man with one heart) at one with ourselves, at one with each other and at one with the almighty.  much hatslacha to all. your success is my success, you will all be in my prayers. kol tov Dan

i have a good friend who is the son of a gadol hador (ok maybe not- he's the son of a big rebbe  ) anyway, he used to have a problem waking up in the morning, one of our friends once asked him "[his name], the rebbe comes to wake you up and yoou just ignore him?"
he answered, "suppose he's not your father, he's still the REBBE but he comes to wake you every single day, would you still have a problem ignoring him?"
i think this answers your emuna issue, think about it

I would like to take a slightly different approach than most people to answering your question.

I think that theoretically, having Yiras Shamayim would help you to stop mast*****. (I would roughly define Yiras Shamayim as a tangible relationship with G-D).
The problem is that Yiras Shamayim is not born overnight by reading a few paragraphs of Chovas Halevavos or Shaarei Teshuva. It is born from many months of learning, but mostly practicing, character change, performance of Mitzvos and learning Torah. The combination of all of the above leads one to building a solid relationship with the Almighty.
The thing is, can a wife expect to build a relationship with her husband while she cheats on him? Even if she washes the dishes, raises his children and does everything else right, her betrayal of her husband is usurping and undermining the fundamentals of the relationship! Even if she wants to stop cheating and find favor in the eyes of her husband, it will take her a long time to do so, all the while scrupulously showing him her devotion and love.

The same is true with us. Trying to build up your Yiras Shamayim on your own will most likely be futile. You can go and learn mussar or chassidus, do mitzvos and learn Torah, but this will not lead to a building of your relationship with Hashem b/c you will not be able to stay sober long enough to do so. If you end up falling into lust while you're trying to build your relationship with Him, what value does it have? What does all your service to Him mean if you're ruining the foundation of the relationship while doing these external things? You need a Rebbi and a good friend to help you get there and they need to know exactly what the issue is and they can help you through with it. I believe that that is what the 12 steps  group essentially is (co addicts and sponsors= Rebbi+Chaver). The less good options are trying the forum and 12 step calls (a step up from the forum) where you can develop relationships with people who can help you get better and change your character traits/ develop Yiras Shamayim.

Who said that אין דבר העומד לפני הרצון means that you can do it by yourself?  Maybe it means, that if you really want to stop, you will ask someone for help. 

(BTW - that statement is not found in chazal.  It is brought in some mussar seforim.)

it not the same b/c if my wife or even a good friend would be watching me EVERY DAY i think i would not fall!! so i;m back to the emuna issue again.

i can't bring my self to go to anybody (1. i'm scared to do it. 2. i am totally embarrassed.) it will not happen anyway.

is Yiras Shamayim enough to stop? If there was an electronic eye following me for my wife to see me it would stop me! so does i mean that i lack yiras shamayim? the answer is probably yes, if so is everything else i do daven learn trying to be mchanech my kids to yes yiras shamayim fake? probably not it would kill me if chas vsholem 1 of my kids should be doing what i do, so the answer is some where in the middle yes i have some yiras shamayim but it is not strong enough to stop me, so the right approach should be working on my yiras shamayim learning musser etc. what do you think? (btw i am clean for six days hoping to get to 90 and then continue)
