Pay Attention to Your Alcohol
Another bad combination with alcohol isn't something a person does to herself, but something someone else does to her. It's rohypnol -- the date rape drug. It's a central nervous system depressant, like Valium, but 10 times more potent, according to the White House Drug Policy web site. It's tasteless and odorless, and dissolves in liquid, so it can easily be put in a beer without you knowing -- slowing a person's psychomotor performance and causing muscle relaxation, decreased blood pressure, sleepiness, and/or amnesia, according to the web site.
"Make sure you watch your own drink," says Berman. "Don't let someone bring you a drink. Watch the bartender when he makes your drink, and don't let it out of your sight."
The problem is the more you drink, the harder it is to be aware of your surroundings, including the beer right in front of your face.
"The difficult thing is when you've had a drink, you're more likely to be less careful and not pay attention and talk to your friends," says Berman. "It's hard to watch your drink and be drunk at the same time."
A few drinks combined with a computer can lead a person to some high-tech trouble with online temptations like Internet shopping and gambling.
"Alcohol makes a person's inhibitions disappear, so they make choices that aren't in their best interest," says Berman. "And, there's something with online gambling and shopping where money doesn't feel real. So when you've had alcohol and your inhibitions are down, it's easier to make impulsive decisions and click a button rather than think about the consequences."
