I have always hated coffee so I've previously had some kind of energy drink in the morning for weeks at a time. Those suckers are bizarrely addictive. It's one thing to have one shortly after you wake up, but I found myself craving them later and later in the day, and of course that makes it harder to sleep...which makes me more likely to have energy drinks the next day. I stopped the daily consumption when I realize…
I mean, you could say the same thing about coffee.
I will say, though, energy drinks do become a relatively expensive addiction. A Monster energy drink can easily cost 3-4 dollars, so if I had three of those a day we are talking $10+ of cost. If you get off brands they're cheaper, but even still I think they're overpriced.
I know it's a meme that people pay like $6 for a coffee at Starbucks, but I think if you buy the coffee beans yourself or instant coffee it's relatively cheap.
