Is it normal to stay awake for 36 hrs after one energy drink
I seem to be completely unable to tolerate caffeine. If I have any amount during the day, it is IMPOSSIBLE to sleep. Today I had an energy drink at 2pm. 12 hours later and I'm still awake, heart pounding. I know I won't sleep again until tomorrow night (technically tonight). Same thing happens with a cup of coffee. What gives? Is this normal?
