Glad you posted first, even though it sounds like you have already decided a "fail" is going to occur.
Don't let that happen. Too often, fails turn to "F**K ITs" and more drinking, and then you'll be coming back here wondering why it's so hard to stop drinking.
Spare yourself the grief. Don't drink and recommit (in writing) to your decision to quit drinking.
