Does Green Tea affect your mood negatively?!

Green Tea contains caffeine. When I consume caffeinated beverages I usually crash several hours later. It's not as pronounced as soda or coffee unless I've been drinking several cups per day, but I notice it. Maybe that's what you're experiencing.

Well if you had some with sugar or like Lipton tea then it could easily be sugar crash. Otherwise, I',m not sure..

Hmm...never had that happen to me. If anything, it even uplifts my mood somewhat and makes me think better.

I guess no, maybe cause of your stress
