I vote sneak attack.
I have gone 30 days twice before and I'm sneaking up on 30 days again. I have usually taken a ride on the pink cloud about this time and rode it for a few weeks or a few months. Eventually the pink cloud will dissipate so like others have said...stay vigilante. I have two different stretches of 7 years of sobriety and like I said, I am sneaking up on 30 days...again. You can't take anything for granted as I have learned the hard way.
Pink Cloud:
The temporary sensation of euphoria and well-being that is characteristic to those who are new to AA and sobriety. For most, the pink cloud eventually dissipates. This heralds the time to get down to business and start seriously working the Steps.
