You might want to experiment with seeing if the down cycle can be shortened and the up one extended. Rather than being surprised by what happens as you gain a degree of control you might discover that you can manage the cycles. Some experiment with sleep cycles and nutrition, others with exercise and supplements, some find different activities can push back. Thomas Edison was supposed to have tried 10,000 different things before he found a carbonized threat for his first light bulbs, and then it only lasted 40 hours. If we are in the "dark" we need to experiment.
