Newbie. Black Mamba Fat Burner Question

Hello everyone. I’m newbie here, but i need advice. Situation: from yesterday i had started taking fat burner Black Mamba. I took 1 pill 1 hour before my workout, but then in night i was not able to sleep. Is it normal or not?
Thank you, guys

Yes, it’s normal for ephedra to impact your ability to sleep; it’s a stimulant after all, that’s what they do.
