Initial treatment for inadequate sleep and various types of “insomnia” is sleep hygiene modification. Certainly, her smoking and nicotine activation aren’t helping, but there’s no such therapy as “setting a date for smoking cessation.” Americans are terrible with sleep, and many who struggle are doing all the wrong things like using electronic devices late in the evening, dealing with neverending light pollution, caffeine and cigarettes too late in the day, going to bed too late, blah blah blah.
