In years of porn abuse, we build tolerance. Tolerance means you don't feel the same high with the same amount of "drug", in our case our drug being porn. All of us remember a time when a little amount of porn made us feel great and then, after year, we need more and more. This is how addictions work, addictions of all kind. Addicts build tolerance and end up consuming big amounts, so big that in the beginning seemed too much.
Binges are, for porn addicts, how we consume big amounts of our drug, namely porn. We built tolerance, we wanted the same high, we consumed more and more until we ended up PMO-ing like 5-7 times a day, plus the escalation of porn which is another subject.
Now you are asking "What can I do about binges?" Well, it's not a simple answer. You have ended up binging to get high because your tolerance had gotten high. It happens to all of us. What to do about it? The answer might not be so simple. Theoretically, all you have to do is never start in the first place. If you don't PMO, you don't binge. Because after years of abuse, we deal with what we call "chaser effect", which means after one PMO, you crave another one so much. Your dopamine levels drop and you feel so low in dopamine that you want to "elevate" yourself and you "think" that another PMO will increase those levels of dopamine and make you stop feeling like that. In the end, you end up doing 7 PMOs in one day. I used to PMO 7 times a day with ease now I would probably get to 5. My age, years of porn abuse or whatever the cause, things don't look well because I seemed to get worse: Less PMOs and a lot more days of "flatline" before the next urges kick in. This is definitely not a bright future.
So back to our problem: The "best way" is to never PMO. That will stop the urge to binge. But it's never so simple. How are you going to never PMO? This is another question and I've been trying for years to figure out a plan to never do that first PMO so I could avoid binges.
