I started using this supplement 3 years ago after a recommendation from a store clerk. It's hard to explain how I was feeling at the time. Agitated, quick to anger and overwhelmed feelings. Before starting any pharmaceutical medications I purchased the supplement and consulted my doctor prior to starting. She said to try it and if I didn't see results within 1 month to return and she had some prescription meds in mind, but all had some not so great possible side effects. Needless to say, I felt so different after 1 week of taking 2 capsules a day. Not only was I less agitated, I had a pep in my step that I did not have for a long time! Fast forward 3 years, I now take one capsule at the same time daily in the morning, non fail. That is all I need to keep that same feeling I had that first week. It has even helped me lose some weight. Nothing major, but I maintain and do not gain. For a while I was gaining year over year. People talk about the price, but honestly it's nothing compared to what we spend on other things, coffee, services and eating out, the list goes on. This is certainly worth a try and if it works for you it will be worth every penny! I have this on auto ship, save money that way and it ensures I will not run out. If Amazon is ever out (it happens) I get it from the original store that recommended it 3 years ago. It's quite a bit more there, but I feel I owe them my sanity! There is no taste and this helps me sleep rather than disrupting my sleep. I have no other side affects.
