FOE!
I started drinking regular caffeinated drinks seven or eight
years ago in the form of nitrous oxide pre-workout drinks
which do not have to publish the caffeine content (100mg
per scoop, I believe, and you take 3 scoops per serving).
Over the last two years I've had those canned store-bought
energy drinks. They actually control my life! One, two, three
a day or until I get a panic attack or feel sick. My sleep is
very inconsistent and I crash hard, overwhelming tiredness like
nothing else. They stopped giving me energy a long time ago
and serve mainly to suppress the depression that overwhelms
me, caused most ironically, from caffeine withdrawal. I've
stolen money, and scrounged pennies into a baggy to be able
to afford them. If it were a hard drug I'd be in an awful mess.
I'm drinking a Monster Energy Extra Strength Killer-B, one of
the few left I'm not entirely sick of and it's my absolute last!
