So for the last three days I have been drinking matcha green tea, supposed to be the strongest of all.
I usually have between 1-4 cups a day.
First day I got a nice wide eye calm alert feeling, the next day some mild alertness, now it seems to have no effect. I even drank a cup after dinner, still went to sleep at my normal time.
Why am I not gettings that nice clean energy back?
Is it easy to build tolerance?
