Living on a college campus can make it hard for me to go to sleep
few things that helps me, not in any order
1. Take Melatonin about 30 mins or an hour before you plan on sleeping, Optium Nutrition sells about 100 days worth for 3 or 4 bucks, I dont remember
2. Make sure room is dark prior to falling asleep, dont just turn out the light then expect to get sleepy quick, give yourself time to get sleepy
3. Make sure room is cool, I have to open a window at night to cool the room down so I can sleep, sometimes I wake up freezing but its better than staying awake
4. No tv or loud sounds close to time you want to go to sleep
5. Don't do anything that takes a lot of thinking before you go to sleep, otherwise you'll be replaying it in your head while you lay there, same goes for stress, it'll keep you up.
And I dont do it but I've heard it works, take a warm shower about 45 mins or so before you plan on sleeping.
Me living on a college campus with loud music playing a few rooms down almost every night, I rarely stay awake more than 10 minutes once I lay down.
