Ive been using this stuff for about 8 months now and now over the last month it has been making me jitter really bad and my heart race. Ive never had this issue taking it before so I think I might stop using it now. My only concern is the placebo affect and that my mind will play games with my body since I wont be taking it anymore. I just dont want my workouts to suffer because of it. But its not worth using if I cant sleep anymore while using it.
