That's what happens when you watch porn on nofap
I suggest doing low-fap instead of nofap, and if you ended up watching porn or some other jewish provocative material then don't fight it like a crusader and just coom and then continue your low-fap.
I tried nofap many times before and every time it was just a few days of very good mood with high confidence and clarity, and then there was explosive fallback to coom with extreme feeling of failure, guilt and depression.
But this time I decided to try something different and instead of going monk-mode like a low IQ fanatic I just decided to avoid porn and erotic material as much as possible, do a little exercise everyday, and resist cooming as much as I comfortably can.
When I've been super horny or super anxious I coomed, but it was just a few times in the past couple weeks and it didn't have that feeling of failure and guilt afterwards because I am allowing myself to do this as a human being.
It's a lot better and higher IQ than nofap.
