Me? No caffeine after 5PM.

Benadryl (as in Tylenol PM and other things) does pretty well....but the real trick is a prescription of Ambien generic. (My HMO covers the generic, but not the Ambien CR (controlled release)so it is quite cheap.I use ½ a 10mg. tab or less, often just ¼. This lasts 3-5 hrs.
So... no caffeine late, Benedryl to get to sleep (takes an hour or more to work), then a piece of Ambien if I wake up because it works faster.

There is also prescription Restoril(Temazepam) on an 'occasional'...once a week or 10 days, because they advise against long-term daily use. I save it for nights when I need, a gentle, easy way to get to sleep.

**disclaimer** I am sort of a test case for drugs. They usually work exactly how they are supposed to for me! My wife is delicate.... needs WAY less of most drugs than the standard does. Some folk need way MORE.

*sigh* when I was young... (like, oh.. 50 or so, I didn't need ANY help getting to sleep)
