Insomnia

I can not sleep';I have bouts of sleep thru out the night,,,maybe getting 2 hours .I try going to bed early...no luck..going to bed late...no luck there either.Why can I not sleep?Theres no big problem I am dealing with...nothing I am worring about.My mind wanders...it does'nt settle on just one thing.I can't read because reading does'nt make me tired...If I were to  read a new book I  wonder what happens next.I 've tried reading books I've already read,thinking I would be bored and therefore become sleepy.Doesn't help because I don't mind reading books I've already read.May be I missed something the first time.My doctor gave me a prescription for a sleeping pill.That works for a while sometimes...but most times it does'nt.Maybe I should take two but I don't think thats a good idea.I watch the damn clock...Hour after sleepless hour.I just want to sleep.
