I gave up porn for 20 days and felt amazing but then relapsed and have been on a porn binge since

Remember when you relapse to write down how you feel

 

Every urge is just you wanting porn. When u decide to quit porn and cut out every bit of arousal from yourself you are free from urges.

How to do it? I dont know. it happened to me only few times

 

wale up early, stay busy all day, during day do not think about fapping, or P, dont even think about it for a minute, only go to bed when your sleepy tired , leave internet accessible devices in other room, close your eyes an sleep

 

Don't put yourself into an unresolvable situation. You think it is an irresistable pleasure but at the same time you shouldn't do it because it is dangerous. This problem cannot be solved by logic. Therefore you start panicing. In panic you don't feel anything and you probably think this panic is the result of the urge. It is not, the panic is the result of the problem.

So you should solve the problem by giving in. 'Ok I will do it whenever I want, even now.'
Don't just say, mean it. Then panic goes away. And you will able to feel better how urge really feels. Hope it helps.
