I'm on day 2 of using these, so take this with a grain of salt... But they are absolutely AMAZING. I will update my review if my opinion changes, but I highly doubt it will.I have struggled with Insomnia my whole life. I've used Benadryl, Zyrtec, Valerian root, Melatonin, Sleepy tea, Estazolam (Prescription), and Ambien (Prescription), and aside from Ambien, these have been the best thing I've ever tried.I stopped Ambien due to fear of dependence, but the first time I took it, I cried from finally waking up *Rested*.... These gummies did the EXACT same thing, but left me without grogginess. I literally cannot get over it. If these continue to work, then they are a miracle. 35 years of struggle. 35 years without feeling rested. 35 years of low energy. Gone because of two little gummies.For me, these are absolutely worth the price because I've never felt this great. However, I totally understand that these are pricey and would say for others these are probably 4 stars because the cost. Other than that, I can't see anything wrong with them. They taste great and they're effective.
