Coming in here when you get that craving to drink is a good idea. And they also have AA meetings in Salt Lake City. Even if you're unsure if you want to participate in AA on a regular basis, going to a meeting is a good way to get out of your own head for an hour or so.
Wishing you the best tonight...
EDIT: Just saw your second post. If you have the option to drive your own vehicle to the job site, then by all means do so. That's a great idea.
