Why after almost 2 years of everyday meditation, all my bad habits like “procrastination” “laziness” and “excessive masturbation” are taking a hold on me ??

Let me tell you all this habits went away or was in control for most of the part, but suddenly everything is coming back and specially the masturbation part, it has come back in full force and taking a toll on me now. What could have gone wrong and what can i do now?
