The way to make yourself relax is to tighten your muscles one at a time from head to foot, tighten--relax, then start counting your way down a looong spiral staircase, ten steps per floor, and with each downward step you tell yourself to relax. I've put myself to sleep many times when my daughters were teens and I went on five hours a night for about seven years while waiting for one or the other to come home from wherever and had to get up early for work. It works.
