What happens if...

Recently I've been feeling strong urges to masturbate without porn, I was curious to know about what happens to all the psychological progress I've had developed from abstaining from it for more than 2 weeks ? Will my confidence etc drop down to when I started or just a little? I don't want to loose my progress as I've felt so good along the journey till now but sometimes the strong urges keep me from having a good night sleep. Some nights are like walking on a rope and preventing myself from falling down. But I try my best to keep away from sexual triggers so I don't make it worse. Does anyone has similar experiences I need some suggestions ...
