Its driving me crazy. I lie awake for hours, absolutely exhausted and just desperate to sleep, getting terrible headaches all day now I guess from the lack of sleep, but of course they in turn make the insomnia worse! I havent been to the doctor about it yet but was wondering if there is anything you can buy over the counter, or any herbal remedies that people have found to work? I'm only 11 weeks so got a long way to go, and if it continues like this I am truly going to go insane!!!
