I haven't begun to practice the tutorials yet. I was reading about the 5th hour of sleep being a good time to try WILD. I wake up almost every night 5 hours after I fall asleep. I was wondering how many others wake up then too, before you started the LD work. I always assume it's my cortisol kicking in. I do some work with hormones and know that cortisol production begins to increase at about 3 AM and peaks at 6 AM. Are there any studies linking LD and or sleep cycles with hormone cycles too?
