Query: Doesn't work :(

This product does nothing for me. I was expecting to be less agitated and happier throughout the day but that hasn't happened. I've noticed (and those around me have too) that I'm still really anxious and stressed and I cry a lot. I tried taking multiple supplements at the same time and it still doesn't have an effect. I won't be buying this again.
