When you felt guilt before, you didn't stop.
There are two types of guilt: Godly guilt, which brings us to repentance, and what I term 'The sorrow of the Damned' - That is, the sorrow one gets when one realizes one is trapped in sin. The second doesn't call to repentance, but simply makes one feel inadequate and like a failure. It makes one think, "I'm just going to fail again."
If you're not feeling guilty, then just stop whatever you think you should. If you fail, then just try again. If you fail again, then just try again. Repeat as often as you need to.
As an aside: You might also try to find out what your trigger situations are and avoid those situations.
All of this is easier said than done, however, because sometimes we frankly don't want
to repent. We want to sin, because it's just so much fun/pleasure/whatever. In that case, it takes a strong man to simply walk away. Be that strong man.
