The answer is simple as ABC. If you've recovered from a certain addictive behaviour, it's not wise to go to the same spot where there might be temptation for a relapse. The truth is, the person just have to avoid any form of activity that would lead to the triggering of the thoughts of what one has engaged in the past. Whether the social gathering is called happy hour or over the moon hour, the person must strive with every fiber of his being to abstain from such environment. No matter the pressure mounting from his friends to do the contrary to his will, must be resiliently declined. Because yielding to the temptation can turn out regretful, because the event might just be an end to his sobriety, and a beginning to another round of battle for substance addiction.
