I have been going through a ton of stress the last 2 weeks with my kids and figured to give it a try. What better to test the Stress tester than when you are actually going through stress. Within in 10-15 min I noticed a change in my mood. Mind you,I have been in "go mode" and stressed out to the max, so I take this when I feel my stress level is about to hit its high. After I take it I feel relaxed and still able to take care of business. I let a coworker of mine have a few drops because her position and duties are stressful and can be overwhelming. She just came to me and raved about how much she loved it, hence this review.
