You drank too much coffee and start to feel bad?
First you have to drink water, stop now and get a huge glass of water and come back.
Drink it all.
Now you have suprised your liver, it most likely haven’t felt the sensation of huge amounts of pure water in 2-3 years.
In 30min/1hour you will pee, nearly all the water out again.
Now drink more water and repeat.
In 1-2 Hours you will feel normal again.
Replace coffee with Tea.
