Downing just about anything to stay awake is nothing new to the college set.

Paul Glab isn't any different.  The USC Junior is part of a growing trend who uses energy drinks for an extra boost.

"During exam week typically when I need to stay awake and pull an all nighter to study for an exam," said Glab.

They come with names like "Monster", "No fear", and "Redline", but Columbia trainer Mike Waldron says you need to know what you're drinking before you pop the top.

"You just have to be smart if you're gonna drink them and not drink too many of them," said Waldron.

Waldron says gym rats use the drinks for an extra kick and b-vitamins, which help convert calories to energy.

But he points out a balanced diet and adequate sleep can do the same thing.

"Energy drinks do not replace a good rest or good night's sleep," said Waldron.

Columbia nutritionist Summer Ortegon who works with competitive athletes points out energy drinks temporarily enhance alertness and performance.

But the combination of caffeine sugar and carbonation in some drinks can increase the possibility of dehydration and lead to possible dependency and other side affects.

Those are lessons student Paul Glab has already taken note of, only downing those energy drinks in moderation.
