I used to fall asleep almost the moment my head hit the pillow and sleep soundly till my alarm went off. For about 3.5 years, I never went into a deep sleep because my son would have breathing problems, so I was always half awake listening for his breathing. One catch in his breath from the opposite side of the house and I'd be sprinting to his room in the dark. (I learned to clear a path before bed)

Ever since then I've had sleep issues. Sometimes I have trouble falling asleep. Sometimes I wake up in the night. Sometimes I wake early. More than a decade later, I'm doing better, but I still have trouble sleeping. I have to sleep in a perfectly dark room with my "hurricane" (sound of wind/waves/brook/rain) with no motion in bed. I sure do miss my perfect sleep.
