I’m struggling to get oat 4 days

I literally just relapsed, at exactly 1:30 AM. I was in bed and I got this urge, I remembered a really hot pornstar from this video, and then all I wanted to do is see her body, and so I did. Looked up the first video i could remember and beat it, with zero hesitation. The thing is I was fine the last 3 days of being porn free. I was consistently working out, studying for exams, focused, hanging out with friends, it was like I didn’t even have an addiction. I need some help, any guidance would be greatly appreciated.
