I want to stop jerking off.

Hi.
I'm nearly in my 20s, finally deciding that I want to stop again properly which most of the time that I could was nearly for a week before giving in to the urge to jerk off again.
Activities that helped me resist were playing on Xbox with my friends and cold showers but I stopped having those last winter 2017 because I was getting headaches from the cold water.
