Darn, sorry to hear it doesn't help you! I've tried a lot of different stuff to try to help me sleep but haven't had a lot of success. Reading something boring that'll help wind you down is helpful I believe. I've heard avoiding blue light a couple hours before sleep is supposed to make a big difference, but I'm addicted to the internet so I've never successfully implemented this to see if it works or not.
Rigorous exercise that'll make you physically exhausted helps.
You could take benadryl on occasion to help fall asleep, but it's unhealthy to take benadryl every night long term. I personally feel worst taking benadryl then if I wouldn't of slept at all, so I avoid it.
A lot of people swear that having a beer or a shot of vodka helps then fall asleep. Given the nature of this forum though I'm a bit hesitant to recommend that since many people here have had substance abuse problems in the past.
