Great use for it!
How was your experience? When I quit caffeine cold turkey, I was miserable. Crazy ass dreams. Headache that wouldn't go away. Two weeks of just total shitty symptoms. Month before I felt totally ok.
Now I'm caffeine free, but holy fuck, that was tough.
Quit caffeine that way. Brutal. Felt like shit for a good solid two weeks. Didn't feel normal for another month.
But I did it and now I'm caffeine-free. :)
