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 had an acute episode over a single, bad, watered down expresso once, where my blood pressure spiked to 22/18. I could have had a stroke, if it wasn’t for timely medical care. Energy drinks don’t have the same effect. So either there is another companion molecule on coffee hitting me wrong or something on the energy drinks changes how the caffeine affects me. Even breakfast drinks with very low coffee content causes me headaches and raised blood pressure.
Maybe you have an allergy to coffee?
No known allergies.
