I quit caffeine for more than 1 year Not a drop was consumed during this period And quitting caffeine has ZERO positive effects except for the fact that your nervous system doesn't get fried 24/7 I drank 15+ coffees a day for 2 years straight so I'm a bit on the extreme side But there's nothing wrong with drinking 3 coffees a day - Better mood - More focus - Faster metabolism The only thing you need to do is get your nutrition under control so the coffee you're consuming doesn't fry your nervous system and turns you into an autistic loser that can't keep eye contact
