I drank coffee for several years (around 4 cups a day, not later than 4pm) and suffered from insomnia and didn’t know the origin. Since I stopped caffeine intake, my insomnia is basically gone and I feel a lot more functional because of better sleep.
So my impression (yeah I have to admit it’s a study of size 1) is rather that caffeine is more dangerous than I thought.
I wonder what it means if I can drink 4 espressos before bed and sleep like a baby... does anyone have research on caffeine metabolisms and ADHD / other diagnoses?
Not everyone is the same. I have heard of drug addicts who could only drop heroin by replacing it with massive amounts of highly-caffeinated energy drinks, in quantities that would be objectively bad for most regular folks.
Yeah I know several people who tell me the same like you... Again not proper science but it seems that caffeine tolerance and metabolism is quite different from person to person.
