This.
If you go to bed and wake up at the same time always, your body will get used to it.
Your brain will know it's time to wake up or sleep.
Also, don't do drugs.
It never helped sleeping.
Oh, drugs help getting to sleep like a beast!
The sleep will be much less refreshing though. You're gonna be pretty tired the next day. x.x
Obviously it depends on the drug, but the ones I have in mind..
