I've started NoFap 50+ days ago and i'm new here but...

around 6 days ago I was about to be on my 47th day, I knew about how to stop the urges, how to transmute my sexual energy into something productive. But I relapsed. I wasn't using the P in PMO but I certainly masturbated no doubt. Then I relapsed again today 6 days in...This kind of urge was new to me, it came suddenly in the dead of night and I was powerless against this new kind of urge. I wanna know how i can stop it. This is the last day I will fap, never again, never..
