I'm pretty okay with getting 4-5 hours of sleep as after my college classes, I can come back and take a nap. However, I've been staying awake until 4-5 AM and dangerously close to 6 AM in the past 2 weeks. I don't know if it's the black tea (honey+sugar) I drink late at night, the mess in my head that keeps me up, or my anxiety, but I would just like to know any tips that help everyone go to sleep quicker.
