I bought the melatonin but the order was placed with the caffeine, not sure whose mistake. Customer service fixed the issue before it shipped! I got my package and opened to find BOTH sleep and energy varieties. I love the melatonin the most, only thing id recommend is laying in bed for a bit before taking it. As with all melatonin, if you stay up after like 45 min of taking it, you'll stay awake or have the sleepless night. Could just be me but noticed this with other melatonin brands (gummies, syrup). Overall, great, fast, effective sleeping 😴 and the caffeine one worked well too!
