My 57-year-old mother has had sleep issues for her entire life, <span style = 'background-color: #dae8f4'>and</span> alcohol
is the only substance proven to help her sleep; nowadays it's the only way she sleeps at all. The rub is that instead of the typical reaction to alcohol before bed (crash, brief snooze, up and
restless just a few hours later), it simply puts her to sleep with no overt ill effects. For as long as she has drank, it has always been this way. Due to this fluke, I can't find any information online about her condition.
