Soberjim, chinaski, ladyb, stay strong! Drinking is a false solution to your problems, only will make it worse tomorrow.
Post here, watch a TV program, call a friend....anything you have to do to not take that first sip.
I'm lucky enough to say I am not tempted tonight - I'm at home and I usually don't have any alcohol in the house, it's the social stuff that is my big temptation - so I'll get through tonight fairly smoothly I think, other than feeling bad about my poor choice last night.
