I've been off coffee for 1 month now. I've drank one or 2 decaff cortado or americanos because I like the taste of coffee, but I feel like decaf doesn't taste as good.
I was a good week with intense headaches, it was scary. I used to drink 1 or 2 a day, nothing more.
As for the link, it doesn't work ... hackernews DoS induced?
