I don't drink caffeine, so that's an immediate no.
Further, if I wanted diabetes, I'd eat a donut. The health risks associated with them is fucking retarded, and anyone who drinks them cares little enough about their own health they might as well take up smoking.

Drinking liquid diabetic heart attacks for "energy" is as dumb as smoking cancerous COPD for "stress relief."

I have no clue what people's obsession with energy is. People drink energy drinks and just sit around watching TV. Retarded.
