What can you take to go to sleep?

Try supplementing with the sleep hormone Melatonin. It's the reason humans are even able fall asleep biologically and, therefore, you'll be able to knock out quickly and naturally. There are no side effects to supplementing with Melatonin but just be sure to take the recommended dosage at all times and only when you're ready to fall asleep. The best part is that it's available OTC. Have fun catching z's!
