Having been trying to get out from under PMO for a long time. Reading some of the posts helped me realize I am not alone in this fight.
Welcome to nofap! My suggestions: * Wear briefs (not boxerbriefs) instead of boxers. This keeps everything secure, and not flopping around where you can be tempted/distracted. * Keep a schedule for your day and don't have unstructured time where you can be distracted/tempted. Make sure you're reading, or going for a walk, or talking to a friend, or getting some work done, and not just lazing around.
