Cures for insomnia

Help! How do you go to bed at a decent hour? Here it is 1am and I just finished making a batch of dish soap. I have to get up before 8am. I find it so hard to get into a routine to go to sleep. It doesn't help that my boys are usually still up around 10pm. I like having some me quiet time (don't even bother saying get up before them and have quiet time; in the am Josh has lowjack on me, as soon as I wake up so does he.)

What is your bedtime routine? How do fall asleep at a decent hour? When do you cut eating out before bed (maybe I eat too close to bed?) Do you exercise during day, if yes what time? Maybe I need to exercise more and not so close to bed. Ahhhhh!!!! I need help and I so need to be asleep.
