Does slow cow work?

My day and night have been completely reversed, and I feel like my body is getting worse, so I'm trying to turn back the day and night cycle. Do people who have tried Slow Cow really sleep? I can't
 sleep at night, so I go to bed every day when the sun rises. I fall asleep while listening to ASMR or book reading broadcasts, but even that takes an hour or two to fall asleep.
 My friend who's in pharmacy school told me to take sleeping pills if I'm going to do that, and my friend who's in engineering school told me to take Slow Cow if I'm going to take medicine. But Slow Cow is somehow easier to approach, lol.
 The dark color is coming down to my chin. Hehe.
