I don't count. I don't do it unless I'm in the mood.
I try to keep a full schedule so I'm busy regardless. This last semester I was a full-time student with some hard classes and also working weekends. I mistakenly worked 40 hours on a hard school week as well. Ended up going 83 hours with 4 hours of sleep.
I've been fapping a bit more lately due to winter break, but that will stop again soon enough.
I've gone weeks or months without doing it before and not realizing it.
I used to play video games 12 hours a day and stay home all the time due to disability, during those times I fapped quite a lot.
Just one of many things I fixed when I decided to get my head right.
