I used to "celebrate" 1-2 days sober with a binge. It makes no sense, it's stupid, but that's what we are as addicts. That's a hard cycle to break, but once you break it, run fast and far. The way I see it is you have 2 choices at this point.
1- Say enough is enough, sober up, no more. Just stop it.
2- Keep up this little game, lose your job, hit a new rock bottom.
