I've been abstaining from PMO on and off for a year or so now, periods of willpower marred by relapses. I think last night might have been the breaking point for me. First, I spent hours that I could have used doing work or other productive things I enjoy chatting on a sex site, and secondly, I was up so late doing so that I came to bed late and my tossing and turning woke up my wife, who had to get up for work. She didn't manage to fall back asleep and so went in for a day of work on about four hours sleep thanks to me. She was so sweet and didn't blame me for it, but I secretly felt terrible, and tried to do whatever I could around the house to make it up to her. When it's interfering with my work and making me feel like a worthless asshole, I say it's definitely time for PMO to go.
