Hello aboodos94, I can tell you about the improvements I've had so far with no PMO for 30 days:
Much better self-esteem, I feel good about myself and I can feel that other people seem to find me sexually attractive, I find myself loads more attractive, I have taken up my hobby of swimming again, I am willing to go to some lenghts to make my life better (healthy eating, tackling problems I had been pushing away, like moving house), awesome boners at night that I didn't use to have, a higher level of overall life energy and clarity, my thinking is clearer.
As for the time it needs to go back to the default setting: I am planning to go 90 days hard mode, so I won't PMO, MO, or edge during that time. 90 days seem to work for most people here. For some it might take longer, espacially if you started out with high-speed internet porn.
Keep truckin', mate. I'm rooting for you. We can do it!
