(AP) -- Chicago attorney Colleen Gorman has a holiday ritual that doesn't involve buying presents or counting down to midnight: She goes online looking for new hangover remedies.

The 28-year-old's fiance tells her she should probably just drink less.

Experts say that's good advice for everyone.

In fact, the only way to prevent a is to not get drunk. But there are strategies to soften the blow.
