I thought about changing this saying to "twenty seconds of ecstasy isn’t worth death, insanity, or permanent injury." When you get an urge to use, follow it through to its horrible end. Any perceived short term reward (is it really a reward?) is not worth the long term punishment. That punishment begins with feeling bad about ourselves and may end with our futile attempt to erase that guilt with more drinking or drugs.
Remember we don't get rid of cravings by giving in to them and using. Using just makes us want to use more.
