Sure try it. But I would assume its about the food you eat and when, your sleep patterns, workouts, not the caffeine.

It's hard for me to give up coffee, but I did it. I drink a cup of matcha at lunchtime. when you give up coffee, it's always extreme at first. But after a few days it gets better and I even feel like I have more energy. But I think you have to try it a least for a month

i think drinking lots of water will help you with get the some of the caffeine out of your system. self, I only have 1 cup of tea in the morning and then I try to drink water for the rest of the day since water balance your energy level throughout the day. but I’m not entirely sure how it all works
