Have been taking Telogenesis for about 2 weeks. I am 67 and have Sleep Apnea that I am in the process of getting that under control. I seem to have more energy at the gym and in the afternoon depending on the intensity of my workouts. I am getting ready for fall elk hunting so some workouts are more intense than others. Heavy days require a midmorning power nap to re-energize but there seems to be more energy available in the afternoons since taking Telogenesis. It will be interesting to see what happens when I can get a full rest full nights sleep. I hope to eliminate those morning naps and not feel tired all the time!
