I won't be taking caffeine at all.Nah man, hot coffee or ice cold coffee will be at your body temperature almost as they hit your stomach and amount of heat transferred to or spent by your body is so minuscule that’s not important (well still don’t chug hot drinks while having hypertermia but neither ice cold will save you from it; lukewarm warm will help just as much cuz hypertermia is often accompanied by dehydration and vice versa).
Caffeine itself taken either before or during MDMA experience is reason for increase in body temperature.
However for me anyway, hot drinks do heat me up..I go red in the face after a coffee.
Just can't handle the heat. I'd be the first to die in the desert but the last man standing in the north pole
