Since 2006 (in uni), when I was first introduced to energy drinks, I've been more or less addicted to them ever since. I even go so far as to regulate my consumption of them in cycles to get the most I can out of it: https://www.rdegges.com/2011/my-use-and-abuse-of-caffeine/
I never really liked the taste of coffee much (without loads of cream and sugar/splenda), so energy drinks were a happy medium because they taste really good, they come in lots of 0 sugar / calorie varieties (which is great when you're trying to stay in shape), and give you a LOT of caffeine per serving which makes me feel super high: happy, productive, focused.
Since 2006, I've probably had roughly 2 energy drinks per day (and over the last few years: maybe 4).
So... This really sucks.
I always "felt" like they were bad for me, but never really did any research as I knew it would most likely make me stop drinking them.
It's surprisingly easy to convince yourself not to look into something so you can continue justifying your actions. But now, I suppose, the fun is up.
It's really time I start being more careful with myself :(
