The first ever, fully optimized, sleep capsules designed to help you experience an even deeper sleep, enhance dream activity and reduce the chance of sleep disruptions caused by the brain and body. PLUS if there is any disturbance in the middle of the night (i.e. getting up to go to the bathroom), you will be able to fall right back to sleep. Sleep Breakthrough Capsules also allows you to wake up in the morning without that foggy brain feeling that you didn’t sleep enough. And those two factors together are a big differentiating factor in success. When you have great sleep, you make better decisions. You have the ability to laterally feel what’s going on. You have a lot more intuitiveness because you’re not fighting all of this chemical buildup that’s been happening overnight. When you get good sleep, you feel like a rock star the next day and your performance is so much higher than it would be otherwise that you don’t really need an outside stimulant.
