I can't seem to get this right again.

First time posting here, but I've been around since late October of 2016. One night my friend was talking about how porn and masturbation aren't the best for you, so I decided to do a bit of research and ended up finding this subreddit. I instantly gave hard mode an attempt and made it to 45 days on my first attempt and I felt great! Now, I can't even get past like a week. I don't want PMO to be a part of my life, but I continuously get 3-7 day streaks. Just looking for some advice, since I clearly need it.
