caffeine is actually a very screwy drug. it's an analgesic and a stimulant. it fucks up your sleep for weeks, the first 4 days after cessation it lowers the pain threshold not unlike opiates. it makes you talkative and impatient, and it also increases muscle signalling and that also takes a month to return to normal as you are weaker for the same period as it takes for sleep to return to normal.
low key, it's heroin's secret little brother how insidiously addictive it is.
