If someone have sleeping problems, you may try it. I took 1 pill for other reason and i slept 16 hours and would be able to sleep another 5 -10 hours. It was super hard to get up. Take it ONLY before going to sleep. Its very sedative. I still feel quite weak, but recovering . Will not take it anymore, effect was too strong. Its also anti dopamine. I was testing some theory, not related to sleeping problems. One study shows that its might be little toxic and may cause breathing problems. so be careful and do research and reddit.
Or a reputable source. 
Well i meant official studies and first hand experience on reddit
