Ex Natural Calming Drink Chillout

I don't understand how I can pass out at night as soon as my head hits the pillow; yet wake up exactly two hours later completely awake. I normally have no problems with my sleep patterns, but this has been happening for the past week or so. Last night after my sudden awakening and consequent tossing and turning, my girlfriend started talking in her sleep. She repeatedly asked me, "What's happening to the front right door?" I still don't know what she was talking about. When I asked her, "What door?" She just said, "This one." and fell into a deeper sleep. At that point I needed to fall asleep fast, so I downed this relaxation drink. I know this variety wasn't made to make me pass out, but it did help. It doesn't have melatonin in it, but the chamomile and Valerian did the trick. This tasted like carbonated Vitamin Water, specifically the guava one (which doesn't really taste like guava). I say thank you Ex. You made my nights sleep a lot better.
