you will feel really sad if you break your promise to yourself....it's only a few hours, you can do it....you don't WANT to drink, so just don't...have something else you enjoy.
someone once posted that a "physical craving" only lasts about 7 mins???? distract yourself, promise yourself some other reward...and feel proud of yourself when you wake up tomorrow AM...be sure to come on and post...I will pat you on the back, I promise!
