At least for me, it was never about Torah, Mitzvohs, shiurim, chevrusas, davening, etc. i am addicted and so what if Mincha is in 20 minutes and i just heard a great shiur i want what i want. Yeah, i'll feel terrible during Mincha if i make it in time or at all but that is "so later" what do i care about it, all that matters is now. The yiddishkeit was something i did(do) because its the right thing to do and even sometimes what i want to do. But above all else what i want to do is give in to my urges as frequently as i can.
Now, for my reasons, i am fighting the urges with tools that are new for me but well proven over the decades. They are working for me, B'chasdei Hashem, 100 days sober. About 80 days more than i was ever able to manage on my own.
If you can't stop then i don't think you need yiras Shamayim, i think you need to work the tools and see what they can do for you. My problem, and maybe yours, is not a low amount of yiras shamayim it is lust addiction. Read the Guidebook and see what steps you need to take for you. Trying to use yiras shamayim to fix addiction is like trying to fix a flat tire with a hammer. A hammer is a useful tool and very good thing to have, but it won't help you in a million years to fix a flat tire.
Hatzlacha in all things GOOD.
