I'm absolutely in love with this sleep complex. This is the first sleep supplement I've taken that doesn't leave me feeling groggy in the mornings. This is because it also has B12 which helps wake you up. I work out early in the mornings, then go through a full work day after drinking pre-workouts or a BANG energy drink packed with caffeine, I take 2 capsules roughly an hour or so before bed time, and I'm able to fall asleep so easily, and stay asleep. No more lying awake in bed until 2am trying to sleep, and waking up in the mornings feeling like a zombie!
