Agreed: Sometimes the thing causing insomnia falls outside the realm of that simple advice (sleep hygiene, exercise, caffeine). Two weeks after being put on Lipitor I began to suffer chronic insomnia for the first time in my life: I had good sleep hygiene (almost perfect), consistent exercise, and minimal caffeine (only in the morning, only before 9am). The problem lay in my body chemistry: insomnia was not an uncommon side effect of Lipitor. The fix? My doctor swapped out Lipitor for a different statin.
