Unfortunately, I was not able to sleep at all, all night. Took my second dose at nighttime, about an hour before bed, and I layed down, closed my eyes, and layed there for hours with my mind racing. I was not asleep at all. I didn't have nightmares or bad dreams, but I couldn't get to a point where I was sleeping either. During the day, I didn't seem to have any adverse reactions. I think I'll avoid prior to bed in the future. Good luck.
