Run your life like a CEO. Plan everything. Even your relapses, so you don't get any surprise relapses.
Or better yet, plan your battles like a general. Always be on the lookout, and when you aren't sure you can defeat an enemy, work around him.
Doesn't matter. One should never relapse out of spontaneity. If you want to edge/relapse. Plan it, set timer, with a minimum of 1 hour. It that time you will have time to think more logical, urges become less.
Everybody should ask oneself: why am I an addict? Is it emptiness, depression, frustration, something else? First learn to deal with that.
The person who treats the symptoms but not the causes of an addiction will only be frustrated and tired of fighting against it.
PMO fooled me once, PMO fooled me twice and even many many times more than that. It won't fool me again.
