Powerful product for energy and focus, but so powerful it seemed to affect my sleep that night

Within an hour or two of taking it I felt a little nauseous and also wired. i almost felt like i was buzzing. It felt very strong to me. However, I didn't get jittery like I have with coffee (I do not drink coffee for this reason, but I do drink 2 cups of black tea/day instead.). I had really good focus and motivation. I felt like it lasted ALL day and I admit I was worried about being able to go to sleep that night. It was hard to fall asleep- my Oura ring showed Latency at 39 min - the highest i've ever had, and a very low sleep score of 71(my average is 83). I also took a melatonin sleep formula before bed. I would only take 1/2 a dose earlier in the day if I took it again.
