Beginning no Fap (need tips)

I'm now 16 and have been letting porn control me for nearly 4 years now. Easily the worst decision of my life. It has made me significantly depressed in the past and many times I have tried to stop, however I have always failed, with my record being around 2 weeks. I recently got into a relationship with my wonderful girlfriend who I would do anything for and I finally feel like I have proper motivation to start no Fap, however I would really appreciate any tips/handy tricks anyone has that helped them. Thank you.
