Physical Danger
Your biggest danger is the demon rum.
It's not going to chase you down or beat you up, but the fact remains: Liquor is a poison. It's not a particularly effective one, but it can kill you if you drink enough of it.
The first thing to keep an eye on is liver damage. You're not going to be drinking enough to get sloshed every day or anything, but you'll be drinking a small amount on most days. It's something to be aware of and could be awfully dangerous down the road.
Speaking of roads, the biggest danger there is drunk driving. Don't do it. Ever. Be aware of what you're putting in your body. If after a sales call you need to go around the corner and wait out the effects, you do that. Maybe you're late to the next appointment, but that's a lot better than dead. Then you're late to everything.
