Like @EndPornLiveLife I quit drinking (about two years ago for me). I found that booze and porn just reinforced each other so it was easier in a way just to quit both. I've mostly stopped watching tv, especially news which was only making me frustrated and depressed, and replaced that by reading a lot more (classics, non-fiction, sci-fi, whatever as long as it is enriching to the mind and soul). I've never been into exercising but now I try to at least take a walk every day to get my body moving and also connect with nature a bit. Most importantly for me is I've begun meditating regularly. It has helped me cope with various chronic problems I have which used to send me into porn as a way of temporarily escaping (which of course in the long run only made things worse).
