I am not a regular consumer of energy drinks. Occasionally, I will buy and drink a can of a specific store brand energy drink, especially when the day is really hot. I enjoy the flavour.
What I’ve been taking note is that, usually, two days after drinking it, I will feel extremely psychically tired. I can sleep normally, even better, to a degree, have more dreams and even feel more mentally active during that period but after those 48 hours, I get extremely tired, to the point I can fall asleep if I stay still for to long. I can maintain myself awake if I remain active.
The drink itself has no unusual ingredients - taurine, guarana, caffeine, ginseng - but for some reason I am still unable to understand, it is the only one that affects me like this.
Note 1: I do not drink coffee. Caffeine from real coffee somehow alters my blood pressure radically. These energy drinks do not.
Note 2: I once drank one specific energy drink - a Battery - that kept me awake and functioning for nearly 60 hours. I was physically unable to sleep. When whatever kept me going ran out I slept for 30 hours straight.
Has anyone ever went through something like this?
I call this effect borrowing energy from the future.
I used to drink around 3 big mugs of coffee a day. Then I just stopped, cold turkey. Took a few months to get adjusted. But what surprised me, is that ALL tolerance to caffeine is gone. If I drink a cup of black tea, I will feel more focussed for a few hours, and less focussed a day or two afterwards.
I now only drink caffeine strategically. If I think todays problems are more important than the next two days problems, I drink some black tea or a cup of coffee. Otherwise I stick to decaf coffee, which fills the habit of drinking coffee perfectly.
What goes up must come down. Cause And effect. I feel this deeply. I been thinking about this a lot. Glad to see someone else nailed it.
