I have had chronic insomnia for my entire adult life. (I'm 65). I'd get 4, sometimes 5 hours of broken sleep each night. Sometimes just 2-3 hours. I was tired all the time and had no energy. I only use half a gummy of the Space Chews at bedtime. I am sleeping all night. I'm getting 7-8 hours of sleep every night!! I feel great! I have energy. I haven't felt tired all day long any more. I also had a lot of trouble with PVC's which compounded the problem. I'd miss so many heartbeats I'd get exhausted. I haven't had the PVC's anymore either. I even went back to work. I had retired because I just couldn't get the energy to work anymore. That's not a problem now! I absolutely love your products. Thank you so much. You have changed my life!!
