I'm taking oral contraceptives but I can't imagine that's what's causing it... it's like it makes more more anxious and really spacey at the same time. If I'm relaxed and tired, though, it works really well. Mostly knocks me out a little quicker and keeps me asleep through the night. Makes me MISERABLE if I'm already anxious, though. Chamomile tea is definitely my first line of defense for anti-anxiety now!
