I have a sister, three years younger than me, who chose to take alarming amounts of pain killers prescribed/obtained illegally from several sources. These would put her into a heavy sleep for over twenty hours a day and she did this for thirteen years of her daughter's life. Her husband, an absolute gem, enabled her to do continue this route as he worked 16 hours a day/seven days a week, took their daughter to and from school, made all of the meals, helped their daughter study-while mom slept. Real doctors said there was nothing wrong with her. When I intervened and cut off all prescription sources she turned to alcohol abuse for two years until one night she passed out, hit her head on a table and had to takke a flight for life helicopter to save her. She suffered brain damage from this incident and now minimizes her substance intake.
