This product is AMAZING. First it tastes really good. I swear it’s improved my breathing over the past week. I never took melatonin previously so I wasn’t sure what to expect if anything. I have ADHD and am usually high strung, I also work a stressful job and have high blood pressure. This little vape made me feel relaxed, lessened my stress, made my body less tense and caused my heart to stop pounding with the rapid force it usually pounds. I was CALM. I was able to take deep breaths and focus. I highly recommend.
