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?
It’s likely you’re not getting enough sleep in those 48 hours after you drink one. Dreams occur in the ‘lightest’ sleep stage, which is also the least restful.
You’re probably still feeling the effects of the energy drink the next day which may be why you feel well rested, even though you’re not. Then after 48 hours you crash and your body wants to catch up on the deep sleep you missed out on for the past two days.
It’s when I dream when usually feel better rested the next day. I get to sleep and enjoy a show.
