I actually tried to quit it permanently once when I was 19.
I was going through a spot of depression thinking I would never get a girlfriend, (My dad has just died as well, to lower my spirits further) so I decided it was best if I just eliminated sexual urges from my life and just become celibate.
Lasted 41 days before I read an article about regular masturbation lowering one's chances of prostate cancer. Needless to say, I immediately resumed anti-cancer operations.
