Is light mode effective or a waste or time?

Hey guys. So I am on day 15 PMO light mode. So I can masturbate but not to any sort of porn or using any previous porn memories as stimulus. I have noticed changes already in my confidence and I am much more at ease in social situations then I was previously. I am also easily able to get a hard on without thinking about porn and dont have the same interest whatsoever in it. However am I cheating by doing light mode? Like I said I have better symptoms but part of me wonder if I will ever rid myself of the demons unless i go hard mode?? Any advice would be more than welcome!!
