To be honest, nofap is easy if you just don't peek and quit thinking that you "must" jack off. If you get triggered -which is easy these times due to constant smartphone usage- you gonna quickly lose your motivation. I get my 1st week done with no urges, it isn't that hard tbh but I stick to that advice and use blockers. The blockers can be misiused, cause if I want I can easily make them off, but their role is to limit the amount of accidentally showing erotic material like ads popping out etc
