I got tired of collecting anecdotes; after a little bit, one more anecdote 'well I kind of sort of felt better although you know I didn't collect any kind of data whatsoever' is just pointless to link to. Sleep is variable, you can see any pattern you want to in a few days, especially with a dab of selection bias. (If I had stopped after 10 days, the means would have looked more impressive; but the p-values tell the truth.)
