  I tried drinking one tablet. I wanted to see whether it really was going to make me more energetic. It was quite effective. I took it in the morning, then I was still wide awake and alert at around 5pm. That is a feat for me. I tend to become sluggish around 3-5 pm; my body starts craving for siesta around that time. So anyway, I was able to work more. I think that energy was sustained till around 8pm. Then I became my usual sleepy self at 9-10. I should take Rogin-E more often.
