Did you track you deep sleep with any tracking device ? That will help you to see the difference when you going to play around with you sleeping stack. Couples of things to add the good exercise like run (up to 3 miles) or sex helping better sleep. Otherwise your stack is looking good just maybe bump melatonin to 1-3mg and you can add the glycine. It is easier to get everything already premix Like that for example Source Naturals Sleep Science NightRest Multi-Nutrient & Herb Complex With Melatonin, GABA, Passion Flower, Chamomile, Lemon Balm & More - Herbal Formula - 100 Tablets  https://www.amazon.com/dp/B0001VVXM2/ref=cm_sw_r_cp_api_i_M1QUEbQVJ9X1Q

Little high in the melatonin otherwise is fine The other thing what you can try is go to bed at 10-10:30 am and wake up at 4-4:30am - works for me
