Anecdote, but I've found that the less I analyze and try to "mold" my sleeping, the better I sleep. The times I sleep worst is when I'm worried about sleeping too little, so whatever I can do to take my mind off how poor my sleep is, the better rested I feel when I wake up.

Some nights are still horrible though, and it's a hard loop to exit when you lie there at 03:43 in the morning and panicking about getting too little hours this night...
