You will be fine. We had a bad incident four years back, and I keep returning. Just be aware, use a reputable driver, and use the same common sense you have at home. There are many, many, many visitors each year, and very few incidents. While this is on no way an informed statistic, I would say you are more likely to have an issue at home than in Jamaica. Lots of the places you'll go to at night will pick you up and take you home with their own drivers, and for extra insurance, use one of the many that post here on the board.
