What is the most quickest way to get a good night sleep?
a good round of sex, a warm shower, and a cold bed with a heavy cover
get in bed an shut ur eyes
Attempt to read Pride and Prejudice in bed. It knocks me out in 3 minutes or less. I really want to get through it, but I just fall asleep.
U can either have sex (...or masturbate a couple times), you can drink some Nyquil which is pretty good at putting you to bed, you can get a heavy blanket and turn the heat down, or warm a glass of milk and eat a banna and make sure you exercise 4 hours before bedtime and no water or caffeine 5 hours before you sleep.
