It's pretty easy to fall asleep if you maintain the same bed time every night, but you probably don't. I recommend looking up military sleep techniques, the US air force has good sleeping techniques that help pilots rest in loud cockpits. Also,
>take L-theanine and melatonin (these have health benefits beyond helping you sleep)
>don't drink coffee / tea for >8 hours before sleeping
>make sure it's not too hot
>use white noise
