Sleepless in cyberworld

I have a hard time sleeping all the time! Now my teen son has been complaining of not being able to fall asleep and then waking up several times after he finally does fall asleep. With back to school around the corner I'm trying to help him solve this problem. The thing is how can I help him when I can't sleep myself? It's very frustrating to say the least. What I don't get is that he has no problem sleeping all day, but he can't sleep at night. I thought insomnia was if you couldn't sleep at all like days at a time. He isn't drinking soda so caffeine is not keeping him up. He doesn't want to go to the doctor for a presciption because he doesn't like to take pills and because of the side affects listed. Also my toddler seems to be having trouble sleeping as well. I think my toddler may have restless leg syndrome cause he wakes in the middle of the night crying saying his legs are bothering him. My husband has restless leg syndrome and I've read that it can run in the family. I have taken him to the doctor but she doesn't think he's old enough to have it.
