Q: Is it safe if I drink a lot of sugar-free Red Bulls?
A: No, it is not safe, even if you are drinking sugar-free.
The caffeine and other ingredients can cause symptoms, and I have personally seen a number of people come to the Emergency Room with rapid heart rates that needed medication to slow down.
Try not to drink more than two in a 24-hour period (or any energy drink for that matter — sugar-free or not).
